The problem

A while ago I posted this:

The configuration information of the performance library "C:\WINDOWS\system32\netfxperf.dll" for the "TFS WorkItem Tracking" service...

But for some reason the problem has returned.

In my previous post I used the /T command-line argument of the lodctr command to set the performance counter service as trusted. Today I have tried a somehow different approach to solve this problem and only time will tell whether this approach helped or not. This is based on the information found in Microsoft KB267831.

In our situation we are talking about the configuration information of the performance library for 4 different services:

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.

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

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.

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

Unload the performance dynamic-link libraries

I opened a command prompt and run the following commands:

C:\>unlodctr "TFS WorkItem Tracking"

Removing counter names and explain text for TFS WorkItem Tracking
Updating text for language 009
C:\>unlodctr "TFS Version Control"

Removing counter names and explain text for TFS Version Control
Updating text for language 009
C:\>unlodctr "TFS Services"

Removing counter names and explain text for TFS Services
Updating text for language 009
C:\>unlodctr "ASP"

Removing counter names and explain text for ASP
Updating text for language 009

Locate the initialization files

Next thing you need to do is locate the initialization files (.ini) for each of the services.

TFS WorkItem Tracking: %programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\WorkItemTracking\bin\WITPerf.ini

TFS Version Control: %programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\VersionControl\bin\VCPerf.ini

TFS Services: %programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\Services\bin\TFPerf.ini

ASP: %windir%\System32\axperf.ini

Update registry values related to performance counters

Run the following commands:

C:\>lodctr "%programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\WorkItemTracking\bin\WITPerf.ini"
C:\>lodctr "%programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\VersionControl\bin\VCPerf.ini"
C:\>lodctr "%programfiles%\Microsoft Visual Studio 2008 Team Foundation Server\Web Services\Services\bin\TFPerf.ini"
C:\>lodctr "%windir%\System32\axperf.ini"

Now let's hope that this solved the problem!
