Two servers: ISA 2006 (domain member) and DC/exchange 2003/DNS etc.

I have had non SSL OWA published for some time and it works great.  Now I have a SSL cert and would like to secure OWA.  My setup is a simple Edge Firewall.  ISA box has one external NIC and one internal NIC.

My OWA site is owa.mydomain.com
My cert is for www.mydomain.com

I know I will get a warning on the cert name when visting, but that is not a concern at this time unless it is why things aren't working.  When I hit my site I get the FBA login home page.  I type in my credentials and then get an error page stating:

Error Code: 500 Internal Server Error.  The target principal name is incorrect. (-2146893022)

When looking at my ISA Monitoring, it logs a Failed Connection Attempt on my OWA SSL Rule.

Is this because my cert is for www. and not owa. or might something else be set wrong?

Thanks

I found this article:

http://support.microsoft.com/kb/328917

Since it is referencing ISA 2000, the settings are slightly different and I tried a few different combinations without luck.

Am I waisting my time or should I be able to do this?

Thanks

The address people use to get to your OWA MUST match the certificate exactly!  So if they are going to https://owa.mydomain.com/exchange, your certificate MUST be "owa.mydomain.com". 

Great Article to help you:

http://www.isaserver.org/articles/2004dmzfebe.html

Scroll halfway down to:  "Exporting the OWA/RPC/HTTP Web Site Certificate to a File and Copying it to the ISA Server 2004 Firewall"

2004 SP2 is so similar to 2006 you won't have any problems.

Good Luck!

Charlie
