SiebelDataControl Login Method On .NET Webservice Crashing IIS

(Doc ID 2141138.1)

Last updated on MAY 23, 2016

Applies to:

Siebel CRM - Version [IP2014] and later
Information in this document applies to any platform.


When using Siebel COM Data Control in a .NET Web Service that is being executed in IIS, the following error is being generated:


Faulting application w3wp.exe, version 7.0.6002.18005, time stamp 0x49e023cf, faulting module sslcnapi.dll, version, time stamp 0x5671dc80, exception code 0xc00000fd, fault offset 0x00071d27, process id 0x%9, application start time 0x%10.


IIS may or may not crash as a result of this error.




As an example, using the following code on VB.NET web service:
Function SiebLogon() As Boolean
  Dim bOk As Boolean
  Dim numberOfTries As Integer
  sibAPP = CreateObject("SiebelDataControl.SiebelDataControl.1")
  bOk = False
  numberOfTries = 0
  While numberOfTries < 5 Or bOk = True
  bOk = sibAPP.Login(SiebelConStr, SiebelUser, SiebelPass)
  numberOfTries = numberOfTries + 1
  If bOk = True Then
  Exit While
  End If
  End While
  If bOk = True Then
  SiebLogon = True
  SiebLogon = False
  End If
  Return SiebLogon
End Function
The same code works fine when run from .NET Windows Forms application on the same machine.

In the machine event log the following entry was generated:
Faulting application name: w3wp.exe, version: 8.0.9200.16384, time stamp: 0x5010885f
