Advanced Server integrates well with existing network systems,
including Windows NT and LAN Manager. Advanced Server provides the
software you need to establish communication between your computers
running Advanced Server and other network computers and resources.
However, because so many choices of protocols and services exist,
you need to know your organization's requirements before
installing Advanced Server.
For two computers to communicate on a network, they must share
at least one network protocol. Before installing Advanced Server,
you will need to know the requirements of your organization.
Local User Accounts |
 |
If your network currently has servers with network operating
systems other than Advanced Server, such as LAN Manager, Version
2.2, you can use local user accounts to permit users of these systems
to access resources in Advanced Server domains.
Local user accounts cannot be used to log on interactively
at a computer running Windows NT Server as a member server or Windows NT
Workstation, but in most other ways are just like regular user accounts.
Local user accounts can connect over the network to computers
running Advanced Server, Windows NT Server, or Windows NT
Workstation. They can be placed in global and local groups and can
be assigned resource permissions and user rights. The one exception
is that local accounts created in one domain cannot be used in domains
that trust that domain — the use of each local account
is limited to one domain.
Create and use local accounts in a domain in the following
types of situations:
To allow users from other Advanced
Server domains to connect to LAN Manager, Version 2.2 servers in
this domain.
To allow users whose user accounts are in untrusted
domains or domains not running Advanced Server to connect to computers
running Advanced Server, Windows NT Server, and Windows NT
Workstation in this domain.
Create a local account in the same way that you create regular
user accounts, with the exception that while creating the account,
use the Account button in the New User dialog box in User Manager
for Domains to designate it as a local account.
For information about creating local user accounts, see Chapter
3, "Working With User and Group Accounts."
How Advanced Server Works with LAN Manager |
|
Advanced Server maintains compatibility with clients running
LAN Manager and at the same time expands and enhances the LAN Manager
server feature set. For example, Advanced Server builds on the LAN
Manager domain model but simplifies domain administration. Instead
of four types of servers, Advanced Server has two; instead of requiring
a user account for each domain, users can have a single network-wide
logon. Similarly, Advanced Server security features build on those
of LAN Manager.
A significant difference between LAN Manager and Advanced
Server systems is that LAN Manager does not recognize trust relationships
and therefore does not allow local groups. To enable user access
to resources on LAN Manager servers in your domain, you must create
local user accounts for all users who are not in your domain but
who will need to use the resources.
To ensure that the correct domain validates a logon request,
MS-DOS LAN Manager clients must be running LAN Manager, Version
2.2c, or later. When clients run software prior to LAN
Manager, Version 2.1, the domain name is not passed and is instead
broadcast throughout the network until a server recognizes the logon
name. Not only does performance suffer, but the user may have accounts
in several domains and may not be validated by the correct domain
controller.
