The other code is 12202. Another bit of information: I'm trying to use the same SSL cert that's on the ISA server for our 2003 OWA site. The names are the same. But we found some reference in a book that says for Exchange 2007 you have to have a different kind of cert that's a lot more expensive. Is that correct? Could this have anything to do with our problem?

ISA *always* provides another code that will be between 2 and 5 digit. What is that other code?

For reference I'm using the article at http://technet.microsoft.com/en-us/library/bb794751.aspx <http://technet.microsoft.com/en-us/library/bb794751.aspx> . I've run into a problem. I guess it's some interaction between the Exchange server and ISA, but I'm not positive, and I'm not sure where to look. We have to coexist with our existing Exchange 2003 server, so that complicates things a bit. Internal OWA DNS points to our Exch07 Hub server. The Hub server then determines if the client is on our Exch03 server or our Exch07 server, and it directs them to the appropriate site. That part works fine. Externally, our OWA DNS points to our ISA server. Exch03 clients get in just fine. Exch07 clients get the authentication box (we've tried it with both integrated authentication and with forms authentication). After correctly entering credentials, we get a 403 Forbidden error message. We are currently set up NOT to encrypt traffic between ISA and the Hub server, but we've also tried it with encrypting that traffic. What are we missing? Is there a better resource to use for publishing Exchange 2007 on ISA 2006? Thanks, Rob -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rob Moore Network Manager 215-241-7870 Help Desk: 800-500-AFSC
