SYMPTOMS
========

The SNA Server Manage Agent service (MngAgent) may fail unexpectedly with an
access violation, causing the SNA Server service to appear in an [Offline]
status.

If Drwtsn32.exe is configured as the Windows NT default debugger on the computer,
the <Ntroot>\Drwtsn32.log entry will be created for the MngAgent failure,
indicating a fault in the routine CStdAgentProxy::SendPending as follows:

  Application exception occurred:

  App: mngagent.exe (pid=<process id>) When: <date> @ <time>
  Exception number: c0000005 (access violation)

  FAULT ->01003641 8b4814           mov     ecx,[eax+0x14]

CAUSE
