Error description
Communications Server for Windows --------------------------------- Crash (blue screen) in appn.sys
Local fix
Problem summary
USERS AFFECTED: All PROBLEM DESCRIPTION: Crash in appn.sys PROBLEM SUMMARY: The root cause is triggered by certain start up sequences which are all lead to CS/Win sending an ACTLU RSP with a TCP/IP control vector (type 0x64). In some case the code (inside appn.sys) corrupts the SNAPS messages which can actually corrupt any part of the SNAPS dynamic memory (buffers and control blocks). The crash occurs at a later point in time (probably within a few seconds) when the corrupted memory is accessed.
Problem conclusion
The source of the corruption has been identified and corrected.
Temporary fix
