code:

System.Security.Principal.WindowsImpersonationContext impersonationContext;
impersonationContext =
    ((System.Security.Principal.WindowsIdentity)User.Identity).Impersonate();

//access network resources.

impersonationContext.Undo();

web.config:

<authentication mode="Windows">       
</authentication>
<identity impersonate="true"
userName="user"
password="password"></identity>

As clear from web.config file, the app runs in an impersonated mode. I need to impersonate temporarily on top of that to access a network resource. I do that as shown above.

This works fine on server if I browse to the website on the local IE installed on the server but when I access the app from my PC or any other PC, I get a access denied.

Btw, this is all within an enterprise domain environment. so IE in both cases is passing a valid authenticated token.

Any ideas what is going on. thanks.
