Event 624: SNA Server Application Exception

 Last reviewed: April 17, 1997
Article ID: Q107382

The information in this article applies to:
  • Microsoft SNA Server for Windows NT, versions 2.0, 2.1, and 2.11

SYMPTOMS

An application exception occurs in SNA Server and a Dr. Watson log is generated. The log shows that exception C0000005 has occurred in module SNASERVR. This only happens when the Attachmate Extra print emulator communicates with SNA Server.

CAUSE

This error is observed when the Attachmate Extra print emulator sends an Open(PLU) response to the SNA Server over it's SSCP-LU connection, rather than the PLU-SLU connection. The OPEN(PLU) response uses the FMI interface which is a trusted interface. Because this is a trusted interface SNA Server does not verify that the destination value is correct. When the PLU session attempts to process the incorrect response, the exception occurs.

RESOLUTION

Microsoft has updated the SNA Server 2.11 file, SNASERVR.EXE, to validate the destination of the Open(PLU) response, rather than simply attempting to process the message.

STATUS

Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 2.11 U.S. Service Pack. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
