a) Are you running multiple applications listening on port 80 (eg if you have multiple IP addresses, and are running multiple webservers)
b) Check your web site identities - you could have a conflicting set of web site identities (each active website must have it's own, unique, web site identity. A website identity consists of an IP address, TCP port and optional host-header name) Cheers Ken ----- Original Message ----- From: "Za Vue" <[EMAIL PROTECTED]> Subject: [ActiveDir] IIS 6.0 AGAIN... : Hi all.
