As far as I know, DHCP is not involved at all in a SSL-VPN connection?
ejhardin,
I do point to local DNS server, either Windows DC if there is one, or else interface DNS (i.e., 10.100.100.1). However, unless the Windows client has the search suffix assigned, the lookups for ' server' instead of ' server.company.local' will still fail. The suffix tells it to search any names entered against that suffix first.
Now, there is a way around this, which is to set Windows itself with a global Primary DNS suffix:
(Win 7 Pro) System Properties -> Computer Name -> Change... -> More...
I have this set for my main company network on my un-managed laptop, however, I connect to three different VPNs, so for the other two I am still SOL. I' m not sure if Win XP supports that same setting or not.
