Manually Configuring NetBIOS Names

Advanced Server/9000 Access

To allow an Advanced Server/9000 to access another Advanced Server/9000 and/or NT Server in the same domain but on different subnets, manually add the Server name and Domain name with their corresponding IP address of the remote Advanced Server/9000 and NT Servers to the Advanced Server/9000 NetBIOS name cache.

Example in a Subnetted Domain:

This example illustrates how to properly configure a NetBIOS name cache on a Advanced Server/9000 to enable functionality in a subnetted domain.

The domain 'SUB_DOM' contains NT and Advanced Server/9000s on multiple subnets. The following servers are in 'SUB_DOM'

AS/U Server 'ASU_Serv1' is on subnet A. Its IP address is 200.1.1.1. AS/U Server 'ASU_Serv2' is on subnet B. Its IP address is 200.1.2.1. The NT Server 'NT_Serv3' is on subnet B. Its IP address is 200.1.2.2.

To manually populate the cache on ASU_Serv1, issue the following commands.

nbutil -a ASU_Serv2 -A 200.1.2.1 -V

nbutil -a NT_Serv3 -A 200.1.2.2 -V

nbutil -a SUB_DOM -A 200.1.2.1 -D

nbutil -a SUB_DOM -A 200.1.2.2 -D

To manually populate the cache on ASU_Serv2, issue the following commands.

nbutil -a ASU_Serv1 -A 200.1.1.1 -V

nbutil -a SUB_DOM -A 200.1.1.1 -D

You can also add entries to the Advanced Server/9000 NetBIOS name cache by editing the /etc/opt/lmu/netbios/nbhost file and executing nbutil -L to load the entries from the file to the cache.

	NOTE: The location of the NetBIOS name cache was moved from /etc/opt//lmu/wanext/nbhost to /etc/opt/lmu/netbios/nbhost. When the name cache is loaded with the nbutil -L or when the name cached is saved with nbutil -S, the file /etc/opt/lmu/netbios/nbhost is used. Move any existing nbhost file to /etc/opt/lmu/netbios/nbhost.

Below are the /etc/opt/lmu/netbios/nbhost file entries of ASU_Serv1 and ASU_Serv2 in the above example:

/etc/opt/lmu/netbios/nbhost file on ASU_Serv1

ASU_Serv2 200.1.2.1 #SERVER NT_Serv3 200.1.2.2 #SERVER SUB_DOM 200.1.2.1 #DOM SUB_DOM 200.1.2.2 #DOM

/etc/opt/lmu/netbios/nbhost file on ASU_Serv2

ASU_Serv1 200.1.1.1 #SERVER SUB_DOM 200.1.1.1 #DOM

	NOTE: Note: It is important to use the -V and -D options with nbutil or the #SERVER, and #DOM keywords in the nbhost file in order to correctly populate the name cache.

Non Advanced Server/9000 Access

To allow a Windows NT 3.51 Server, Windows NT 3.51 Workstation, LAN Manager 2.2c client, or a Windows 95 client to access Advanced Server/9000s in the same domain but on a different subnet you must use at least one of the access methods listed below:
