Hi I have been receiving the following message in my application event log

"The configuration information of the performance library "C:\WINDOWS\system32\netfxperf.dll" for the "TFS WorkItem Tracking" service does not match the trusted performance library information stored in the registry. The functions in this library will not be treated as trusted."

Does anyone know how to resolve this?

Hi Peter,

Have you had any luck resolving this issue?

There is a link to the similar problem: http://support.microsoft.com/kb/267831/EN-US/

Hope it helps.

Thanks, Valery.

It seems to happen at 7:00am every day and I get the following 4 events in a row!

The configuration information of the performance library "C:\WINDOWS\system32\netfxperf.dll" for the "TFS Services" service does not match the trusted performance library information stored in the registry. The functions in this library will not be treated as trusted.

It might actually need extensive troubleshooting to find the cause, and you might want to contact CSS by calling 800/936-5800 if from US (see <http://support.microsoft.com/> for calling from other countries) - They can help by spending a lot more time with various troubleshooting than forum answerers and you won't have to wait for replies to your post.

Ok, many thanks for your help. I will see if I can call them, but am not sure if I have any support credits left.

If I resolve it I will post back.
