We are logging by name and all is going well. ISA 2000 SP2 and FP1 have been installed. Our only problem now is OWA so our user can have access to their exchange email from any workstation. We have a link on our home page that points straight to the OWA page and they get prompted for username and p/w. When they put in a username/pw it takes them to the OWA page and they get prompted again, and then authentication fails. I have set IE to bypass proxy server for the ip of the Exchange box. But when I put out a sniffer, requests are still going through the ISA. Digging a little deeper with the sniffer, they are getting an authentication error INET 401. When authentication is set to basic, they can connect to OWA, but in integrated - they cannot. Any thoughts? Thanks Shane
