Hi,

I don't understand why Profiler now throws error code 2 -- file not found -- when in previous versions it would show an error code to do with a logon failure (1381, etc).

But you may want to check your computer's local security policy to make sure the ASPNET user has the 'logon as a batch job' right. Also check the event logs for errors of source 'userenv'. If the ASPNET user's profile is corrupt, you can't change it until the profile is deleted and recreated.

On IIS 5.x, ANTS does a batch logon as ASPNET to modify the user environment.

The quickest foolproof workaround is to profile the web app using webdev.webserver.exe:
