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= ) When: @ Exception number: c0000005 (access violation)
