Advanced Server Key Descriptions

Alert Parameters Entries

The Registry path that contains entries for the Advanced Server Alerter service is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services	    \AdvancedServer\AlertParameters

AlertAdminOnLicenseOverflow REG_DWORD 0 or 1

Specifies whether the server sends an administrative alert message when the maximum allowable number of clients is exceeded.

Default: 0 (message will not be sent)

You can change the value of this key using the AS/U Administrator.

AlertUserOnLicenseOverflow REG_DWORD 0 or 1

Specifies whether the server sends a message to a client that tried to link but failed when the maximum allowable number of clients was exceeded.

Default: 0 (message will not be sent)

You can change the value of this key using the AS/U Administrator.

File Service Parameters Entries

The Registry path that contains entries for the Advanced Server file service is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

	\AdvancedServer\FileServiceParameters

AclCacheSize REG_DWORD 0 - 100

Specifies the number of entries in ACL cache which keeps track of the results or recent access checks performed on Advanced Server resources.

Default: 6

EnableSoftCompat REG_DWORD 0, 1, or 2

Specifies how Advanced Server handles file opens in read-only compatibility mode. Use 0 to keep the compatibility mode; 1 to translate to read-only/DenyWrite mode for files with special extensions (for example, .EXE, .COM, and .BAT) specified by the value of the EnableSoftFileExtensions key; and 2 to translate to read-only/DenyWrite mode for all file opens.

Default: 1

EnableSoftFileExtensions REG_MULTI_SZ List

Specifies the file extensions for which the compatibility mode will be translated to read-only/DenyWrite if the value of the EnableSoftCompat key is set to 1.

Default: bat com exe dll cmd

ForceDirectoryAcl REG_DWORD 0 or 1

Determines whether Advanced Server will create an access control list for a newly-created directory if an explicit access control list was not provided by the client computer. If an access control list is not created, one will be inherited automatically from its parent directory whenever it is needed.

Default: 1 (create new access control list)

ForceFileAcl REG_DWORD 0 or 1

Determines whether the Advanced Server will create an access control list for a newly-created file if an explicit access control list was not provided by the client computer. If an access control list is not created, one will be inherited automatically from its parent directory whenever it is needed.

Default: 0 (will not create new access control list)

ForceFileFlush REG_DWORD 0 or 1

Specifies whether to force a UNIX fsync(2) system call when an SMB flush request is received. Not forcing fsync(2) system calls can improve file server performance; files will be flushed automatically to disk by the UNIX fsflush daemon periodically, regardless of the setting of this key.

Default: 0 (will not force fsync system call)

IgnoreUnixPermissions REG_DWORD 0 or 1

Gives users the option to bypass UNIX system permissions when working with files and directories. For example, enabling this option would allow Advanced Server users to write to or delete files for which they have sufficient Advanced Server permissions even though only UNIX system read permissions had been granted to those files.

Default: 0 (enforce UNIX system permissions)

You can change the value of this key using the AS/U Administrator.

MappingSeparator REG_SZ Character string up to 7 characters

Specifies the string that will be appended to the file name before its unique suffix to indicate that the name is mapped. This value matters only in UNIX system to Windows NT file name mapping. The default is a tilde (~), the same as in UNIX system to 8.3 mapping, but it is possible to set it to enable the client to easily identify files containing characters illegal in Windows NT. By default, a file named "my?" will be mapped to "my_~xyz." When the value of this key is set to "~asu~", the name will be mapped to "my_~asu~xyz". If an invalid parameter is placed in the Registry, the MappingSeparator will be replaced by the default value.

Default: ~

You can change the value of this key using the AS/U Administrator.

MaxFileSizeInKB REG_DWORD 100 - infinity

The maximum file size, in KBytes, that Advanced Server will allow a user to create on the server.

Default: 20000

MemoryMapFiles REG_DWORD 0 or 1

Specifies whether the server uses the UNIX system mmap system call to memory map file data into the server's address space for efficiency. File mapping is attempted only for read-only files.

Default: 1 (memory map read-only files)

MixedCaseSupport REG_DWORD 0 or 1

Specifies whether mixed-case support is enabled on the server. Mixed-case support allows clients to access file names containing uppercase characters on the UNIX system. Enabling mixed-case support may negatively affect the server's performance.

Default: 0 (make all file names lowercase)

You can change the value of this key using the AS/U Administrator.

NameSpaceMapping REG_DWORD 0, 1, 2, or 3

Specifies the type of file name space mapping enabled on the server.

A value of 0 indicates that there is no name space mapping enabled.

A value of 1 specifies that only UNIX system to 8.3 mapping is enabled. This allows 8.3-style clients, such as MS-DOS, Windows 3.1, and Windows for Workgroups, to access files with long file names and file names containing characters that are invalid in DOS ( + , ; = [ ] ? " \ < > * | : . [space] )

A value of 2 specifies that only UNIX system to Windows NT mapping is enabled. This allows Windows NT-style clients, such as Windows 95 and Windows NT to access files with file names containing characters that are illegal in Windows NT (? " \ < > * | :).

A value of 3 specifies that both UNIX system to 8.3 and UNIX system to Windows NT mappings are enabled.

Default: 0

You can change the value of this key using the AS/U Administrator.

OplockTimeout REG_DWORD 1 - infinity

The interval of time (in seconds) that the server waits for acknowledgment from a client of an "oplock" broken notification.

Default: 30

ReadAheadCount REG_DWORD 0 (always read ahead) - infinity

The number of sequential file accesses by a client that the server must detect before it begins reading ahead.

Default: 2

ReportNTFS REG_DWORD 0 or 1

Specifies whether to report share UNIX system volumes as NTFS or actual UNIX file system type.

Default: 1 (report as NTFS)

RootOwnsFilesCreatedOnNFS REG_DWORD 0 or 1

Specifies whether files on NFS are owned by root or user.

Default: 1

You can change the value of this key using the AS/U Administrator.

SyncAclFileOnWrite REG_DWORD 0 or 1

Determines whether the server will force changes to the access control list (ACL) file to be written to disk using an fsync(2) system call or whether the server will permit the operating system to write the changes to disk normally.

Default: 0 (write ACL changes to disk normally)

TruncatedExtensions REG_DWORD 0 or 1

Specifies whether to replace the last character of the file extension of a mapped file name with a tilde (~). This key applies to file extensions which originally were longer than 3 characters. This feature can be used to distinguished longer file extensions from similar 3-character extensions that were unchanged. For example, enabling this feature prevents a file named file1.document from being mapped to a file named file~xyz.doc which could cause some clients to consider this file a Microsoft Word file. (This key affects only UNIX system to 8.3 file mapping.)

Default: 1 (Do not replace last character with a tilde.)

You can change the value of this key using the AS/U Administrator.

UniqueSuffixLength REG_DWORD 0 to 7

Specifies the length of the alpha-numeric suffix appended to the file name to guarantee the mapping uniqueness. The longer the suffix, the higher the probability that the mapped name is unique. If the mapped name is not unique within a directory, name collisions may occur. They may cause the client to be denied access to the file it needs, or the client may get access to a different file than the one it requested.

It is not advisable to set UniqueSuffixLength to a value less than 3, unless the preservation of a longer file name prefix outweighs possible name collision problems.

Default: 3

You can change the value of this key using the AS/U Administrator.

UnixCloseCount REG_DWORD 1 - 20

The number of least-recently accessed open files that the server closes transparently to avoid reaching the UNIX system's per-process limit. The server uses a technique called file descriptor multiplexing to allow clients to open far more files than the per-process limits would normally allow.

Default: 5

UnixDirectoryCheck REG_DWORD 0, 1, or 2

Specifies whether Advanced Server will allow clients to write to UNIX system directories that do not have write permissions. Microsoft client software treats the "Read-Only" attribute as advisory and does not limit the behavior of directories. In contrast, the UNIX system treats "Read-Only" permissions as mandatory and prohibits users from writing in directories for which they do not have write permission.

A value of 0 allows writing only to directories with write permissions; a value of 1 allows writing to directories belonging to or created by Advanced Server (as determined by checking group memberships of directory); and a value of 2 ignores UNIX system directory permissions.

Default: 1

You can change the value of this key using the AS/U Administrator.

UnixDirectoryPerms REG_DWORD 0 - 511

The UNIX system permissions for newly-created directories.

Default: 509 (0775 octal)

You can change the value of this key using the AS/U Administrator.

UnixFilePerms REG_DWORD 0 - 4095

The UNIX system permissions for newly-created files.

Default: 1460 (02664 octal)

You can change the value of this key using the AS/U Administrator.

UnixQuotas REG_DWORD 0 or 1

Specifies whether Advanced Server provides UNIX system disk quota support. This ensures that creating or writing to the file is performed under the UNIX system UID of the UNIX system user to which the Advanced Server user is mapped. Each action counts toward that user's quota; an error message is sent to the client when the quota is exceeded. Two quotas are supported: i-node and block quotas for HFS file systems. This is true to the extent of the ability of these file systems to support UNIX system quotas.

Default: 0 (no support for disk quotas)

UseNfsLocks REG_DWORD 0 or 1

Specifies whether the server tries to set UNIX system record locks in files as requested by clients. Record locks may not work on NFS files on a server running NFS. If the value of the UseUnixLocks key is 0, this feature has no effect on the server.

Default: 0 (do not set locks)

UseOplocks REG_DWORD 0 or 1

Specifies whether Advanced Server grants opportunistic locks to clients who request them on opens.

Default: 1 (use opportunistic locks)

UseUnixLocks REG_DWORD 0 or 1

Specifies whether record locks created by clients are reflected in the UNIX file system.

Default: 0 (locks are not reflected in UNIX file system)

You can change the value of this key using the AS/U Administrator.

WriteBehind REG_DWORD 0 or 1

Specifies whether physical UNIX system writes are performed before or after the server responds to the client. If UNIX system writes are performed before the server responds to the client, then the server appears to be slower (because the response is delayed), but the server can report disk full errors to clients. If UNIX system writes are performed after the response is sent, disk full errors during write SMBs are not reported to the client.

Default: 1 (enable write behind)

Net Administration Parameters Entries

The Registry path that contains entries for the Advanced Server Net Administration is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

	\AdvancedServer\NetAdminParameters

NetAdminGroupName REG_SZ Character string

The UNIX system group name assigned to the net admin \\servername /c command.

Default: DOS----

NetAdminPath REG_SZ Character string up to 256 characters

The UNIX system path used to find commands submitted by the net admin \\servername /c command.

Default: /var/opt/lanman/bin:/bin:/usr/bin

NetAdminUserName REG_SZ Character string

The UNIX system user account name assigned to a process executed by net admin \\servername /c.

Parameters Entries

The Registry path that contains entries for the Advanced Server Parameters is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

	\AdvancedServer\Parameters

CheckPrintQueueInMinutes REG_DWORD 1 - infinity

The interval in minutes at which the server determines whether a printer queues should be started.

Default: 10 minutes

DisableUpLevelPrinting REG_DWORD 0 or 1

Specifies whether to disable or enable Windows NT-style printing.

If you chose to disable Windows NT-style printing during an upgrade procedure, resulting in the setting of this value to 1, then you can enable this feature by changing this value to 0. See the Advanced Server/9000 Concepts and Planning Guide for more information about Windows NT-style printing.

Default: 0

MaxDirectoryBufferSize REG_DWORD 1 - infinity

The maximum size of a buffer that the server will use for a getdents(2) system call to read the contents of a UNIX system directory. Because Advanced Server will attempt to allocate these buffers using the GC memory allocator, one should consider increasing the SizeGcBufferPoolInKB key if one increases this value.

Default: 16384 bytes

MaxIpcTryCount REG_DWORD 1 - infinity

The number of read() system calls after which the server checks to see if other work could be done by the server. There is a considerable amount of interprocess communication (IPC) between server processes. The server uses the read system call to receive IPC messages, but read does not always return the entire message. This key ensures that the server does not keep trying to get an IPC message at the expense of other activities the process could perform.

Default: 20

MaxMailslotReadTime REG_DWORD 1 - infinity

The amount of time in seconds to wait for a local mailslot application to read a class 1 mailslot. A value specified here keeps the server from waiting indefinitely for a message to be delivered.

Default: 90 seconds

MaxMessageSize REG_DWORD 1024 - infinity

The maximum amount of data that a client can exchange with the server.

Default: 4356 (bytes)

MaxPrintQueueNameLength REG_DWORD 1 - 255 characters

Provides dynamic control of the allowable length of the name of a printer queue. LP subsystem commands currently allow class names to be as large as 255 characters, but jobs sent to these classes cannot be controlled and many of the UNIX system commands to manipulate these jobs result in a fatal error. This key is used by printer queue functions to restrict access to queues based on the length of the queue name.

Default: 14

MaxRawSize REG_DWORD 8192 bytes - infinity

Specifies the maximum size (in bytes) of the raw send or receive buffers that the Advanced Server will use for processing Read Block Raw, Write Block Raw, Transaction, Transaction 2, or NT Transaction SMBs.

Default: 32768

MaxServiceWaitTime REG_DWORD 5 seconds - infinity

Specifies the amount of time (in seconds) the server will wait for a service to respond when it changes the following statuses of the services: pause, continue, install, uninstall.

Default: 60

NativeLM REG_SZ Character string

An additional field in the session setup request/response. This field is generated at run time.

Default: Advanced Server for HP 9000 Systems

NativeOS REG_SZ Character string

An additional field in the session setup request/response. This field is generated at run time.

Default: UNIX B.10.20

SendByeMessage REG_DWORD 0 or 1

Specifies whether the server sends a message to every client in the domain in the event that it is going to stop for any reason other than a normal shutdown. The message states that the Advanced Server has stopped.

Default: 1 (send a message)

SizeGcBufferPoolInKB REG_DWORD 1 - infinity

The buffer size in KBytes allocated for each server process for client files.

Default: 300 (KBytes)

Specifies whether the server can create a core dump file on disastrous failures.

Default: 1 (create core file)

KeepSpareServer REG_DWORD 0 or 1

Specifies whether the server should have a spare lmx.srv process available for another client. New client connections are likely to be quicker if this key is enabled.

Default: 1 (start lmx.srv process)

LockNapInMSec REG_DWORD 1 - infinity

Specifies the length of time in milliseconds that the server sleeps when shared memory lock contention occurs. The server retries busy locks at intervals specified in this key until the length of time specified in the value of the MaxLockTimeInSeconds key elapses.

Default: 10 milliseconds

MaxLockTimeInSeconds REG_DWORD 5 - infinity

The maximum interval in seconds that a server process waits for a shared memory lock to become available.

Default: 300 seconds (5 minutes)

MaxVCPerProc REG_DWORD 0 - 101

The maximum number of virtual circuits that each lmx.srv process should be able to handle. This limit normally is calculated on the fly by Advanced Server using the value of the VCDistribution Registry key and the value of the maxclients parameter in the lanman.ini file. If the value of this key is non-zero, its value is used instead of the calculated value.

Default: 0 (Use value of VCDistribution key)

MaxVCs REG_DWORD

The maximum number of virtual circuits that can be established to an Advanced Server computer. This key permits administrators to manually override the sizing of shared memory. Do not change the value of this key.

MinSmbWorkerTasks REG_DWORD

Determines how many SMBWORKER tasks are preallocated by lmx.srv processes on startup. Do not change the value of this key.

MinVCPerProc REG_DWORD

The minimum number of virtual circuits that each lmx.srv process should be able to handle. This limit normally is calculated on the fly by Advanced Server using the value of the VCDistribution Registry key and the value of the maxclients parameter in the lanman.ini file. If this value is non-zero, its value is used instead of the calculated value.

Default: 0 (Use value of VCDistribution key)

NumCIStructs REG_DWORD

Sizes the CLIENTINFO array in shared memory.

Do not change the value of this key.

NumCLIENT_SESSION REG_DWORD 5 - 128

Limits the number of trust relationships that a server can maintain with other domains. This figure should be at least one greater than the number of domains trusted by the server's domain.

Default: 5

NumHashTables REG_DWORD 8 - infinity (powers of 2)

The number of buckets for the hash table in shared memory to keep track of the various modes that clients have used to open files and set record locks.

Do not change the value of this key.

Default: 128

NumSERVER_SESSION REG_DWORD 5 - infinity

Limits the number of servers and Windows NT clients that can authenticate with the server. This figure should be large because it limits the number of Windows NT clients that can contact the server. On a primary domain controller, it must be at least the number of servers and Windows NT clients in the domain.

Default: 100

NumUStructs REG_DWORD 1 - infinity

The number of structures allocated in shared memory to handle record lock and open file records. The sum of open files and record locks cannot exceed the value of this key.

Default: 1000

SpareServerTime REG_DWORD 0 - infinity

The interval in seconds that a spare lmx.srv process is allowed to run without serving a client before being terminated.

Default: 120 seconds (2 minutes)

StopOnCore REG_DWORD 0 or 1

Specifies whether the lmx.ctrl process is to stop if it finds that an lmx.srv process has terminated unexpectedly.

Default: 0 (do not stop Advanced Server)

VCDistribution REG_MULTI_SZ List

Specifies the distribution of virtual circuits or sessions over lmx.srv processes. The architecture of the server allows multiple sessions to be served by each lmx.srv process on the UNIX system. The server must decide if a new session should be handed off to an existing lmx.srv process or if a new process should be started. This key specifies the distribution of sessions over the lmx.srv processes.

Values are entered in sets of three integers separated by commas, each set of three number on a new line. In each set, the first number specifies the number of clients; the second is the minimum number of virtual circuits each lmx.srv process should support; the third is the maximum number of virtual circuits each process should support.

Default: 1,2,12

ShareCacheCount REG_DWORD 5 - infinity

The number of share names to store in the sharefile cache.

Default: 40

ShareReadCount REG_DWORD 1 - infinity

The number of share entries to read during sharefile operations. Setting this value greater than 1 causes the server to read ahead SHAREENTRY structures from the sharefile.

Default: 10

User Service Parameters Entries

The Registry path that contains entries for the Advanced Server User Service Parameters is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

	\AdvancedServer\userServiceParameters

CreateUnixUser REG_DWORD 0 or 1

Automatically creates and assigns a similarly-named UNIX system user account to every new Advanced Server user account created in the domain in which the server is a member. The value of this key must be set to 1 on every server on which UNIX system accounts are to be created. Note that new Advanced Server users are assigned to the UNIX system lmworld account.

Default: 0 (do not create UNIX system user account)

You can change the value of this key using the AS/U Administrator.

Exclude REG_SZ Character string

Specifies existing UNIX system user IDs excluded from being assigned to Advanced Server user accounts. If an Advanced Server user account is created whose name matches an existing UNIX system user account whose ID is contained in the exclude list, a new UNIX system user account will be generated automatically and assigned to the Advanced Server user account. This can be used to ensure that certain existing UNIX system user accounts never are assigned automatically to newly-created Advanced Server user accounts, even if the ForceUniqueUnixUserAccount key is set to 0.

Default: 0 - 100

ForceUniqueUnixUserAccount REG_DWORD 0 or 1

Specifies whether to assign automatically an existing UNIX system user account to a newly-created Advanced Server user account. If you select 1, then the system does not assign existing UNIX system user accounts. Instead, new UNIX system user accounts are generated automatically and assigned to Advanced Server user accounts when they are created.

Default: 0 (A new Advanced Server user account can be assigned automatically to an existing UNIX system user account with an equal or similar name, provided that the UNIX system user account is not specified in the exclude list.)

GroupUpdateTime REG_DWORD 0 - infinity

The interval in seconds at which the server checks the UNIX system file /etc/ group for changes.

Default: 3600 seconds (1 hour)

NewUserShell REG_SZ Character string

The login shell for new user accounts. The default prevents new users from logging into the UNIX system using a terminal emulator. To enable login, set this key to a real value, such as /bin/sh.

Default: /bin/false

SyncUnixHomeDirectory REG_DWORD 0 or 1

Whenever the home directory of an Advanced Server user account changes, this key changes the home directory of the associated UNIX system user account to match the Advanced Server home directory.

Default: 0 (do not synchronize home directories)

A list of the user accounts and computer names that should receive administrative alerts.

Default: None

CountNotOnNetworkCache REG_DWORD 0 - infinity

Specifies the number of non-running cached clients to which the Alerter service should not send messages. When the Alerter service tries to send a popup message to a client, NetBIOS name resolution can cause unwanted delays if the client is not on the network. To circumvent this problem, the Alerter service caches the names of clients that are not running and does not send alerts to these clients.

Default: 10

You can change the value of this key using the AS/U Administrator.

IncludeMessageHeader REG_DWORD 0 or 1

Specifies whether the Alerter service should add four lines of header information to messages (sender, recipient, subject, and date).

Default: 0 (do not include headers)

You can change the value of this key using the AS/U Administrator.

Indicates the interval in seconds at which the master browser ages its browse lists and updates its lists with the domain master browser.

Default: 720 seconds (12 minutes)

You can change the value of this key using the AS/U Administrator.

MoreLog REG_DWORD 0 or 1

Indicates whether the Computer Browser service should record additional system log entries for events such as election packets that the Computer Browser service receives and the role of the browser server (master or backup).

Default: 0 (do not record additional entries)

You can change the value of this key using the AS/U Administrator.

Default: 0 (server is visible)

You can change the value of this key using the AS/U Administrator.

LmAnnounce REG_DWORD 0 or 1

Specifies whether a server should announce itself with the old LAN Manager-type announcement in addition to the new Windows NT-type announcement. This key has an effect only if the value of the Hidden key is 0.

Default: 0 (Use only Windows NT-type announcement.)

You can change the value of this key using the AS/U Administrator.

LogonAlert REG_DWORD 0 - infinity

Specifies the number of logon violations that can occur before the server sends an alert to the alertnames list.

Default: 5

You can change the value of this key using the AS/U Administrator.

Specifies the interval in seconds at which the server announces its presence to the network. This key has an effect only if the value of the Hidden key is 0.

Default: 180 (3 minutes)

You can change the value of this key using the AS/U Administrator.

SrvComment REG_SZ String up to 48 characters

Specifies the descriptive comment that the server sends when it announces its presence to the network.

Default: Advanced Server for UNIX

UserPath REG_SZ Path

Specifies the UNIX system directory on the server to be used as a default parent directory for home directories for new user accounts.

Default: c:\home\lanman

Net Logon Service Parameters

The Registry path that contains entries for the Advanced Server Net Logon service is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\
Parameters

LogonQuery REG_DWORD 60 - infinity

Specifies the interval, in seconds, at which the server checks if linked clients are still active.

Default: 900 (15 minutes)

You can change the value of this key using the AS/U Administrator.

Pulse REG_DWORD 60 - 3600 (1 hour)

Specifies the interval, in seconds, for sending update notices when no updates are occurring to the master user accounts database. This keyword applies only to a primary domain controller and is ignored by other servers.

Default: 300 (5 minutes)

You can change the value of this key using the AS/U Administrator.

QueryDelay REG_DWORD 1 - infinity

Specifies the interval in seconds that a client can wait before responding to the server's inquiry about whether it is active.

Default: 2

You can change the value of this key using the AS/U Administrator.

Randomize REG_DWORD 5 to 120

Specifies the time period in seconds within which a backup domain controller randomizes its request to a PDC for updates after receiving an update notice. This keyword decreases the odds of servers in the same domain requesting an update from the primary domain controller at the same time.

Default: 30 seconds

You can change the value of this key using the AS/U Administrator.

RelogonDelay REG_DWORD 1 - infinity

Specifies the interval in seconds that a client can wait before logging back on to the server after the server has been stopped and restarted.

Default: 2

You can change the value of this key using the AS/U Administrator.

Scripts REG_EXPAND_SZ

Specifies the location of the logon scripts directory.

Default on primary domain controller: %SystemRoot%\var\opt\asu\lanman\shares\asu\repl\export\scripts

Default on backup domain controller: %SystemRoot%\var\opt\asu\lanman\shares\asu\repl\import\scripts

You can change the value of this key using the AS/U Administrator.

SSIPasswdAge REG_DWORD 86400 (24 hours) - infinity

Specifies the time, in seconds, at which a backup domain controller must change the password that it sends to the primary domain controller to verify its eligibility to receive user accounts database updates.

Values: 604800 (7 days)

You can change the value of this key using the AS/U Administrator.

Update REG_DWORD 0 or 1

If this value is set, the server synchronizes the user accounts database with the primary domain controller every time it starts. This keyword applies only to a backup domain controller and is ignored by the primary domain controller. Note that full synchronization is a very time-consuming operation.

Default: 0 (do not synchronize)

You can change the value of this key using the AS/U Administrator.

Replicator Service Entries

The Registry path that contains entries for the Advanced Server Directory Replicator service is as follows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

	\Replicator\Parameters

ExportList REG_SZ Character string

Lists an unlimited number of servers or domains that receive notices when the export directory is updated. These servers subsequently replicate from the export server. If no value is specified, the export server sends a notice to its domain. Separate multiple names with a semicolon (;). This value is ignored if the value of the Replicate key is 2 (Import).

Do not use the UNC name when you specify a computername; that is, do not include two backslashes (\\) at the beginning of the name.

Default: (local domain name)

ExportPath REG_SZ or REG_EXPAND_SZ Pathname

Specifies the export path. All files to be replicated must be in a subdirectory of the export directory. This value is ignored if the value of the Replicate key is set to 2 (Import).

Default: C:\var\opt\asu\lanman\shares\asu\repl\export

GuardTime REG_DWORD 0 to one-half of Interval

Sets the number of minutes an export directory must be stable (no changes to any files) before import servers can replicate its files.

This option applies only to directories with tree integrity.

Default: 2

ImportList REG_SZ Character string

Lists an unlimited number of servers or domains from which files and directories are to be replicated. If no value is specified, files and directories will be replicated from the server's domain. Separate multiple names with a semicolon (;). This value is ignored if the value of the Replicate key is 1 (Export).

Do not use the UNC name when you specify a computer name; that is, do not include two backslashes (\\) at the beginning of the name.

ImportPath REG_SZ or REG_EXPAND_SZ Pathname

Specifies the path on the import server to receive replicas from the export servers. This value is ignored if the value of the Replicate key is 1 (Export).

Default: C:\var\opt\asu\lanman\shares\asu\repl\import

Interval REG_DWORD 1 to 60

Specifies how often in minutes an export server checks the replicated directories for changes. Used in conjunction with the Pulse key. Ignored on import servers.

Default: 5

MaxFilesInDirectory REG_DWORD 0 to infinity

Specifies the maximum number of files in an import directory that can be replicated.

Default: 2000

Pulse REG_DWORD 1 to 10

Specifies in minutes how often the export server repeats sending the last update notice. These repeat notices are sent even when no changes have occurred, so that import servers that missed the original update notice can receive the notice. The server waits the equivalent of (Pulse * Interval) minutes before sending each repeat notice.

Default: 3

Random REG_DWORD 1 to 120

Specifies the maximum time in seconds that the import servers can wait before requesting an update. An import server uses the export server's value of Random to generate a random number of seconds (from 0 to the value of Random). The import server waits this long after receiving an update notice before requesting the replica from the export server. This prevents the export server from being overloaded by simultaneous update requests.

Default: 60

Replicate REG_DWORD 1, 2, or 3

Specifies the Replicator action, according to the following:

1 = Export — the server maintains a master tree to be replicated.

2 = Import — the server receives update notices from the export server.

3 = Both — the server is to export and import directories or files.

Default: Varies with role of server

TryUser REG_DWORD 0 or 1

Specifies whether the import server should try to update directories when a user name is logged on locally.

Default: 0

UnixDirectoryGroup REG_SZ Character string

Specifies the UNIX system group account name for replicated directories.

Default: DOS----

UnixDirectoryOwner REG_SZ Character string

Specifies the UNIX system user account name for replicated directories.

Default: lmxadmin

UnixFileGroup REG_SZ Character string

Specifies the UNIX system group account name for replicated files.

Default: DOS----

UnixFileOwner REG_SZ Character string

Specifies the UNIX system user account name for replicated files.

Default: lmxadmin
