I have a site to site VPN over the internet with ALL servers at the "main" site. The firewall sends 100% of the traffic to the remote side. "remote" site has a firewall and switch, that's all. The firewall does DHCP and hands out the "main" site DNS servers. Once I am logged in everything works well, but when I try to login with the network plugged in it says unable to locate domain controller. If I unplug then log in with the cached credentials it lets me in, I plug in LAN and am good to go, can ping by name and go to unc paths etc. Is there something I have to do to allow it "more time" to find the DC or what is going on?
Clients are mostly XP, a few Win7 and servers are all 2003
