Hi,

I get several PerLib and PerfNet errors in my eventlog. When I run procesmon I see a lot of access denied errors for my app pool accoount in the registry on performance keys. Anybody any idea how to get rid of this?

Try adding your app pool account to the local Performance Monitor Users group.

The application pool account is already in that group.  The user has no rights (read or write) on any of those keys. When I add the user to a specific performance folder in the registry with read rights some errors are gone. But the account also tries to write to the performance sub key folders in the registry. Te problem is gone when I give full control but I don't want to do this for every registry key.

These are some of the messages I get in the eventlog

PerfNet 2004: Unable to open the Server service performance object. The first four bytes (DWORD) of the Data section contains the status code.
PerfLib 1008: The Open Procedure for service "BITS" in DLL "C:\Windows\System32\bitsperf.dll" failed. Performance data for this service will not be available. The first four bytes (DWORD) of the Data section contains the error code.

I tried to rebuild the performance lib following some blog articles, msdn and technet articles.

No solution yet.

Hi Danny,

Did you use SQL Server 2014 with SharePoint 2010?

If yes, then you can install April 2014 CU for SharePoint and then check if the error still occurs.
