Problem Starting the Profiler in Frame work 1.1


I have installed ANTS Profiler, on my system I have .Net Frame work 1.1 and 2.0 . In Frame work 2.0 it is working fine, but when I am running on Frame work 1.1 it is giving error message like this.

"Problem Starting the Profiler.

The user the ASP.NET process is configured to run under must be different to the currently logged on user.

Please check the event log for more details"

What is the reason, where I have configure to run on Frame work 1.1

    ANTS Profiler, when profiling IIS5+ASP .NET 1.1, needs to work around an issue in order to work correctly. It does this by enabling profiling for all processes run by a particular user. This is generally a bad idea if the ASP NET user is logged in interactively, because all processes (including Profiler!) will run almost too slowly to be usable.

    This doesn't happen with .NET 2.0.
  • We needed to go in the machine.config file and specify another user account for the ASP.Net process to run under. Its in the processmodel section.

    That's certainly one solution. The ASPNET account needs to be different from the logged-in user and this is how you would change it.
