SYMPTOMS
The SNA Server Configuration Tool (Svconfig.exe) does not update the following registry entry to include the valid NameSpace values for the SNA Server transports that are chosen   HKEY_LOCAL_MACHINE \SYSTEM \CurrentControlSet \Services \SnaBase \Parameters \NameSpaces: REG_MULTI_SZ: where the entries in the are the DLL names listed below, listed on separate lines in the registry editor Multi-String Editor Data field. The valid NameSpace values for the various transports are shown here:

TCP/IP: ipbcast.dll

IPX/SPX: nwsap.dll

Microsoft Networking (Named Pipes): lmbcast.dll

Banyan Vines: bvnsst.dll

AppleTalk: atnbp.dll

For example, if named pipes and TCP/IP are chosen, the entry will appear as   NameSpaces: REG_MULTI_SZ: lmbcast.dll ipbcast.dll NOTE: The Server Configuration Tool (Svconfig.exe) included with SNA Server 3.0 can be used to change the following SNA Server settings:
 * Subdomain Name
 * Server Mode
 * Transports



CAUSE
The Server Configuration Tool as originally written did not update the NameSpace value in the registry.



RESOLUTION
Use either of the following two methods to work around this problem:
 * Use SNA Server Manager to change the SNA Server Transports instead of the SNA Server Configuration Tool.

-or-
 * Manually add the appropriate NameSpace value to the registry after making a change to the Transports using the SNA Server Configuration Tool.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

The SNA Server Configuration Tool has been modified to correctly update the NameSpace value when making a change to the SNA Server transports. The following file has been updated:

\System\Svconfig.exe



STATUS
