I installed .net framework 2.0 on the server (SBS2000). The first thing I noticed was a "Perflib" problem under the Application Log of the Event Viewer: "The Open Procedure for service "ASP.NET" in DLL "C:\WINNT\Microsoft.NET\Framework\v2.0.50727\aspnet_perf.dll" failed.  Performance data for this service will not be available. Status code  returned is data DWORD 0." A second problem was the installation did not create "Microsoft .Net Framework 2.0 Configuration" link under Administrative Tools on Start menu. I tried both repair and reinstall it. The problems still exist! Help!!

I'm having the same problem.  I searched high and low.  Your the only posting I have found.  I have also posted on MS NewsGroups with no luck.

Have you figured out a way to fix it yet?

Thanks.

Despite the event log error message, do ASP.Net actually work? 

How often do you get the logs in the event log?

Thanks,
Leonid

Unfortunately, I don't know what caused your computer to start generating those errors, but I believe these steps will probably fix them.

1. Uninstall all versions of ASP.Net by running "<frameworkdir>\v2.0.50727\aspnet_regiis -ua".

2. Then, run RegEdit, and go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ASP.NET and \ASP.NET_<some_version>.  If these keys don't exist, skip the next step (step #3).

3. Delete ASP.Net and ASP.NET_<version> keys.

4. Install ASP.Net by running "<frameworkdir>\v2.0.50727\aspnet_regiis -i -enable"

I found this link that gives more info about this error:  http://www.eventid.net/display.asp?eventid=1008&eventno=70&source=Perflib&phase=1

To find out how you got into that state in the first place, I'd be interested to know if you have other versions of ASP.Net on your machine, and if so, in what order you installed or uninstalled them.

I installed the .Net 2.0 SDK (since I found the "Microsoft.NET Framework2.0 Configuration" menu link on my workstation uses a different path than the previous .Net Framework - now is under "C:\Program Files\...")on the SBS2000 server (even though I don't want to install it on the server - just see if that help). Now, I got "Microsoft.NET Framework2.0 Configuration" menu created under "Administrative Tools". However, the "Perflib" error still full of Application Log. I have change the Application Log properties to have it "Overwrite events as needed" since it gets full (over 2000) pretty quick! The problem is unsolved.

Yes. I have .Net Framework 1.1 installed. If I remove that version of the .Net Framework, current (version 1.1) running application will stop working. I don't have any beta versions of the Framework installed on the server. The Application Log get full pretty quickly. It constantly generate the errors. Now I am trying to uninstall the version 2.0 Framework SDK and the Framework as you recommended. I am not sure if current running .Net Framework 1.1 and its update will cause any problem to version 2.0. It was said we can run them at the same time without any problems, is it right?

The problem remains unsolved after the "aspnet_regiis -ua" and "aspnet_regiis -i -enable"!

After you ran aspnet_regiis -ua, did you see if the ASP.Net perf counter registry keys mentioned in my post above are still remaining?  If so, go ahead and delete them.

No ASP.Net left after the "aspnet_regiis -ua" - All gone! When I reinstalled .Net 2.0 Framework, the the system started generating the same errors.

What is the identity of the worker process?  You can see this in Task Manager by selecting the Processes tab.  If the "User Name" column is not visible, you can add it by going to the View menu and selecting "Select Columns".

1) net localgroup IIS_WPG /ADD

2) net localgroup IIS_WPG "NameOfWorkerProcessIdentity" /ADD, where NameOfWorkerProcessIdentity is the name of the worker process identity.

3) open regedit (or regedt32 on Windows 2000).

4) navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ASP.NET_2.0.<bld#>\Names

5) right click and select Permissions.

6) click Advanced

7) click Add and grant IIS_WPG the following permissions:

   * Query Value

   * Set Value

   * Create Subkey

   * Enumerate Subkeys

   * Notify

   * Read Control

8) iisreset

I could not find the worker process. I think I removed ASPNET user and changed something in the machine.config file. I has been working fine with ASP.NET 1.0 and 1.1. Is that will be a problem for installing .Net Framework 2.0?

On a Windows 2000 domain controller, you need to follow the steps in my previous post in order to fix the problem with the performance counters.  The worker process name is aspnet_wp.exe.  This will probably be fixed, eventually, in a hotfix or service pack.

Thanks,
Thomas

tmarq,

We are having this exact same problem on a customer's SBS2000 server.

I followed your list of instructions, but unfortunately it made no difference.

Some comments:

I got an error for Step 2 saying that the user was already added.

Using regedt32 I had to select "permissions" from the window menu and give IIS_WPG Full Control.

Any ideas?

Thanks

Update: I retraced my steps and found that I had performed Step 2 incorrectly. Once I typed in the command correctly I did not get an error.

However, after I did the iisreset again I found the Perlib errors were still being logged.

What is the worker process identity?
