SYMPTOMS
========

The Event Viewer Application log indicates a large number of the following stop
events:

  Event ID 1008
  Source: Perflib
  Type: Error
  Category: None
  Description: The Open Procedure for service "MSExchangeDS" in DLL
  "C:\EXCHSRVR\bin\perfdsa.dll" failed. Performance data for this service
  will not be available. Status code returned is DWORD 0.

  Event ID 1009
  Source: Perflib
  Type: Error
  Category: None
  The Open Procedure for service "MSExchangeDS" in DLL "perfdsa.dll"
  generated an exception. Performance data for this service will not be
  available. Exception code returned is DWORD 0.

  Event ID 1011
  Source: Perflib
  Type: Error
  Category: None
  Description: The library file "C:\EXCHSRVR\bin\perfdsa.dll" specified
  for the "MSExchangeDS" service could not be opened. Performance data for
  this service will not be available. Status code is data DWORD 0.
  These events will be repeated for several DLLs associated with various
  Exchange services.

CAUSE
=====

One possible cause for this behavior is that DLLs associated with performance
monitor have hung. The problem was traced to link monitors running against the
Exchange Server computer.

RESOLUTION
==========

Reboot all servers that have the link monitors running against the Exchange
Server computer. After the servers have been rebooted, the errors should stop
appearing in the Event Viewer.
