If I go to this website: http://216.213.98.98/report/displayclubfrieda.asp Via a MS Proxy 2 SP1 server with or without the proxy client, it never offers me an authentication box and I go straight to the "Error: Access Denied." If I use the ISA server I have as a proxy (no firewall client NOT SecureNAT), I get prompted for my credentials and get in just fine. Any ideas on why this isnt working through the proxy Server? On the ISA I have a protocol rule for FTP, HTTP and HTTPS. On the proxy server (Web Proxy) I allow the account to FTP and WWW.
