DOCUMENT:Q165534 13-JUN-2001 [sna] TITLE :Link Service Not Configured with Short Length of Service Title PRODUCT :Microsoft SNA Server PROD/VER:WINDOWS:3.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - 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.
