SYMPTOMS
If the SNA Server connection (supporting the APPC LU's being requested) does not start for any reason, the SNA Server returns an invalid sense code in the SENSE_DATA field. However, if the remote system receives an actual SNA sense code during the LU6.2 session activation, SNA Server returns the correct sense code in the [MC_]ALLOCATE response.



CAUSE
If a connection fails, the SNA Server service returns the value of an uninitialized variable to the APPC interface, instead of a valid sense code.



RESOLUTION
To correct this problem, apply the fix mentioned below.



STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11, and 2.11 Service Pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack.
