Cannot create or delete the Performance Category 'C:\Windows\TEMP\tmp3DA0.tmp' because access is denied.
After migrating some .NET applications from an old server to a brand new Windows Server 2019 instance, we stumbled over a range of errors.
Yesterday we got one step closer to a solution but we are not there yet. The application still doesn’t work but now we get the following error message:
Server Error in '/AppServices' Application.
Cannot create or delete the Performance Category 'C:\Windows\TEMP\tmp3DA0.tmp' because access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.UnauthorizedAccessException: Cannot create or delete the Performance Category 'C:\Windows\TEMP\tmp3DA0.tmp' because access is denied.
ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

I couldn’t find a ‘good’ solution to get rid of the error message above. In the end I did 2 things to get rid of the error:
- I temporarily gave the application pool accountAdministrator rights on the server.
- I gave the application pool account ‘Write’ permissions on the following registry path: Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\
After creating the performance counters on startup, I revoked these permissions.
Anyone with a better solution?
