I have a VPN 3005 setup to allow the SSL client login. 2 weeks ago we started having trouble with Outlook. The SSL clients authenticate and establish the tunnel just fine. When they try to start Outlook they get a message stating that the server is unavailable. Looking at the Exchange log, it seems like the domain is being stripped before being passed to the domain controller. I tried turning the strip domain option off in the concentrator, but still had the same problem. The full VPN clients are working just fine. The issue only seems to affect the SSL client. Does anyone have any idea what the problem might be?
I have this problem too.
