SYMPTOMS
========
If an invokable APPC TP is not configured as a Windows NT service using
Tpsetup.exe, then loading the invoking TP (such as Sendtp.exe or Randomtp.exe)
may cause an application exception in Snaservr.exe in function s1pxsnd(). When
this problem occurs, a Dr. Watson log similar to the following may be
generated:
Application exception occurred:
App: snaservr.exe (pid=<process id>)
When: <date> @ <time>
Exception number: c0000005 (access violation)
<data omitted>
