SYMPTOMS

If the .NET Framework is installed on a system that is running Windows XP, any process that uses the Performance Data Helper (PDH) functions to retrieve performance counters may stop responding ("hang") for 60 seconds when the process exits.

CAUSE

This delay is caused by a bug in the .NET Framework performance extension DLL, Mscoree.dll.

RESOLUTION

To prevent the delay, you can turn off the .NET Framework performance counters:
  1. Locate the following key in the registry:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\.NETFramework\Performan
  2. Change the Library value from mscoree.dll to donotload_mscoree.dll.
If you later decide to turn on the .NET Framework counters, change the Library value back to mscoree.dll.
