When trying to access web server published by ISA I get the subject error... :( I know this topic is posted (relatively) often... I've read every single posting, mskb, etc.... I haven't found the solution yet... what else can I try to resolve the problem? Any ideas? Details: - All-in-one box config (W2k SP3 as DC, Exchange 2k SP3 & OWA, ISA 2k SP1) - Trying to publish OWA using SSL - Works like a chard from Inside the LAN - Get the "proxy chain look" when accessing from Outside What I've already done: - OWA is on only web site on server - Binding order (in Network & Dial-Up -> Advanced -> Advanced Settings) does have internal NIC first - IIS is listening on only internal NIC (socketpooling disabled) and default ports 80 (http) and 443 (https) - Incoming SSL listener configured in ISA server properties - An ISA Destination Set includes external NIC (with the 3 OWA directories: /ExchWeb/*, /Exchange/*, and /Public/*) - Web Publishing Rule says to forward request to above Destination Set to the internal NIC address, and specifies SSL bridging too (SSL to be forwarded as SSL) - ISA Routing Rule (the default only) configured to send SSL requests as SSL - OWA directories set up with Basic Authentication in IIS Heeeeelp!
