Snaserver.exe May Trap in Function S1PXSND()

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)
