We are running IPSec between a PIX and a 7200 (with the ISA card). We are unable to add active directory domain controllers across the IPSec tunnel. The error we get says "Could not find the domain controller for this domain." Ping, ftp, etc. all work between the two boxes. Also, when we ran the tunnel between two PIXs, it worked. Is this a well known problem?
More than likely it is a DNS problem. So far in our AD preparations 9 out of 10 problems is DNS related. If everything else is working that's where I would look. I sincerely doubt it has anything to do with the tunnel. As we are doing it with "no" problems.
