How to Change the Subdomain Name in SNA Server

MORE INFORMATION

The information concerning which subdomain an SNA Server belongs to is stored in both the registry and Snaexp.snav. Snaexp.snav contains information regarding the size and position of the main SNA Server Manager window, as well as which part of a subdomain is displayed in each multiple document interface (MDI) window and the size and position of the MDI windows. Therefore, several steps are necessary in order to complete this modification.

The registry information is located at:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SNABase\Parameters\ 
   SNADomain REG_SZ: <subdomain name>
				

Perform the following steps on each SNA Server participating in the subdomain:

1. Stop all SNA services.
2. Run the Svconfig.exe utility which which is found in <snaroot>\system directory.
3. Change the SUBDOMAIN NAME field to the desired one.
4. Apply change and click OK to exit.
5. Restart the SNA services.

Perform the following steps where SNA Manager has previously run:

1. Delete the file SNAEXP.SNAV located in the <snaroot>\system subdirectory.

NOTE: This file will get recreated when SNA Manager is restarted.

NOTE: For SNA clients that are configured to resolve the location of SNA Servers via subdomain name, an additional change will be required on the client workstation to reflect the new subdomain name. If this change is not made, then clients will not be able to locate a SNA Server and fail to create a sponsor connection. No chnages are required for clients that are configured to locate a server by name.
