Question : Error Code: 403 Forbidden The server denied the specified Uniform Resource Locator (URL).

After much fidiling I've managed to get to the ISA login screen used to publish our sharepoint site, but once I put the domain name and password into the ISA screen I get:-

Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)

Is this a IIS configuration problem or with the actual sharepoint application? Any help would be gratly appreciated.

Answer : Error Code: 403 Forbidden The server denied the specified Uniform Resource Locator (URL).

what kind of authentication have you set in ISA? basic?
look at IIS for sharepoint, and make sure authentication is the same there as well, if you have basic on ISA you must have Basic on web page as well
