Hi All,

Yesterday I keep getting the following ASP.Net error log in the Windows 2000 server in the Event Log:

---------------------

The Open Procedure for service "ASP.NET_2.0.50727" in DLL "C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet_perf.dll" failed.

Performance data for this service will not be available

---------------------

I have googled it and found the following documentation which seems to have a solution.

http://support.microsoft.com/kb/555129

It suggested to change the Permission of the Registry Key for "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib".

But as I browse through the regsitry using regedit in my local XP machine, right click on key and the premission option is there.
But this option is not available on Windows Server 2000, simply permission is not available when right click on Registry Key.

I have also used regedt32 and there is a security option in the toolbar but it cannot browse the User Access Control List.

So is there any way to fix this error on Windows Server 2000 which running both websites on both .Net 1.1.4 and 2.0?

The Open Procedure for service "ASP.NET_2.0.50727" in DLL "C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet_perf.dll" failed.

Many Thanks.

Hi,

Based on my understanding, you get the error message above in the Event Log of Windows 2000 server. If I have misunderstood you, please feel free to let me know.

If any performance counter object in the performance library is not available, the error message occurs. There are a couple of suggestions, which you can follow.

I hope this helps.
