Link Service Not Configured with Short Length of Service Title

• Microsoft SNA Server, version 3.0

SYMPTOMS

When configuring link services on SNA Server Manager, if the link service title string is less than 11 characters, you will receive the following messages:

Link Service Error - This link service cannot be configured using SNA Server manager. To configure this link service, run the External Link Service tool from tools menu.

CAUSE

The DWORD variable containing the size of a buffer used to store a registry value wasn't being set, and therefore the value containing the link service DLL name could not be determined.

RESOLUTION

This fix sets the buffer to the size it was before calling RegQueryValueEx.

WORKAROUND

You can change the link service title to a length greater than 11 character in the registry.

The value in the registry is:

   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services
      \SnaSdlcx\Parameters\Title 

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
