Changing User

[Hari potter]

Hi all,

I have an asp.net website that references some dlls. The web site has
been configured to use anonymous access(with windows credential user
name and password) and also Windows Authentication. When I am running
the web site, On trying to bind to the dll, I am getting an access
denied error. I can see that it is running as "NT AUTHORITY\SYSTEM".
How can I change it to run as my user acccount ? I tried
impersonate=true with authentication mode as windows..Does not Help
....Any ideas how to change it ?

here is the stack trace
