  • Sorry, it is Win 2008 with Exchange 2007 and acts as a DC.  It was installed as part of EBS and thus the dual rolls.

  • Hi,


    Thank you for your post here.


    From the description, you receive the Event 1004 that indicates the pautoenr.dll raised an exception.


    Do you have the Event log that says taskeng.exe crashes?  For app crash issue, we generally need to analyze the performance monitor logs and memory dump files to locate the root cause. Unfortunately, debugging is beyond what we can do in the forum because of the nature of forum support. A support call to our product service team is needed for the debugging service. I'd like to recommend that you contact Microsoft Customer Support Service (CSS) for assistance so that this problem can be resolved efficiently. To obtain the phone numbers for specific technology request please take a look at the web site listed below:;EN-US;PHONENUMBERS


    If you are outside the US please see for regional support phone numbers.

  • Hi,

    Not sure if this thread is still being monitored.  We recently started seeing the same issue and yes, it comes with taskeng.exe log entries.  Since you mention this I assume it has been seen before.  What do you know about this issue?
