Active Directory 2003 use over VPN tunnels to branch offices.
Posted on 2007-10-12
Ok, I have a fully integrated active directory running on 3 Windows 2003 servers over VPN tunnels. I have the primary master at the data center in the corporate office. The other 2 servers connect to the corp. office through Cisco 1811 dual wan routers (VPN). Each server at all 3 locations are DNS servers for that local network. The gateway for corp. is 192.168.0.1 and the other two branch sites are 192.168.1.0, and 192.168.2.1&. Everything works fine and should always work given that the tunnels stay up. But I did some testing and seen that when the VPN tunnels are down the branch servers cannot connect to active directory or does the local DNS seem to work.
My main question is this& Is there a way to maybe transfer zones or something, so that when the networks cant communicate with the corp. server and the servers are rebooted the DNS and active directory still works for that local network? The branch servers also run very slow when it cannot talk with the primary master.
