SNA Server May Log Event 23, Qualifier 0x000A

• Microsoft SNA Server version 2.11 Service Pack 1, and 3.0

SUMMARY

When using SNA Server 2.11 Service Pack 1 (SP1) with a remote link service (which communicates to a distributed link service running on a "remote" computer running SNA Server), SNA Server may log Event 23 with a qualifier code of 000A. This code is not documented in the "SNA Server Reference Guide:"

  Event:  23
  Source: SNA Server
  Description: Connection TOKEN1   using Link Service SNAREM1  failed
               Qualifier = 000A

CAUSE

This qualifier can occur if:

   The server running the distributed link service has been powered off or
  has failed.

  -or-

   The LAN session between the remote link service and the distributed link
   service has been lost. To diagnose the cause of a LAN disconnect, a
   Network General Sniffer(TM) or Microsoft Network Monitor trace of the
   LAN session disconnect should be captured.

MORE INFORMATION

If a connection failure occurs, SNA Server logs Event 23 to the Windows NT application event log, indicating a "qualifier" code that provides information on the cause of the failure. These qualifier codes are documented in the "SNA Server Reference Guide."

However, a qualifier code of 000A is not documented in the SNA Server Reference Guide, because this special code is returned by the remote link service that is new with SNA Server 2.11 Service Pack 1.
