Editing machine.config has no effect

[OnTheAnvil]

I've been trying to get past a security problem by editing the processmodel section in machine.config. I have .net 1.0 and 1.1 installed so in both files I changed the username and password to a valid username and password on the local machine. Noithing happened. When I went to Task Manager the aspnet_wp.exe is still running as username = ASPNET not the username that I changed it to in the machine.config. I ended the process and it didn't change. I started and stopped IIS and still no change. Finally I set the username and password to completely random values and still no change. Am I missing something?

 

My web server is down right now so any help would be appreciated.

 

Thanks,
