Re: Permission denied problem. please help me

Impersonation only allows access to local resources as the user who's using your site. You want delegation which will allow off-host access as the user who has authenticated in the browser. In essence it means you need to enable this in AD for the machine that's running your webserver. Check out this for more info:
