Webbrowser control

Hi is it possible to impersonate another domain user using

System.Security.Principal.WindowsImpersonationContext

with the web browser component so that users can browse as themselves without logging on the machine or the application

I have tried this a couple of times and the web browser control only seems to work with the host user not the impersonated user. When impersonating the page fails to render and the activeX control seems to keep retrying the page.

thanks in advance for any time spent on this.
