Interesting Issue...

[reynolwi]

Ok i have 2 domain controllers and 1 exchange server, both domain controllers are global catalog servers because they are in different locations. 1 domain controller holds all the roles and the other domain controller is at another location in town and they connect via a VPN Tunnel. I know the tunnel works because i can move around and everything on both sides and all DNS is working and both subnets are functioning correctly. 1 domain controller is at 10.25.18.0/24 and the other is 10.25.19.0/24

My question is this because i found it interesting. When i go to AD Users and Computers from a computer in the 25.18.0 subnet it connects to the other domain controller on the 25.19.0 subnet all the time. Even connected via remote vpn into the server at 25.18.0 from some other place it still connects to the other domain controller at the remote site. Why is this primary? I know cause i have seen this in the event logs that the other remote domain controller thinks its the master browser and it keeps fighting for the role but that cant happen cause the pdc emulator retains that role. I looked in WINS and have verified that the domain master browser is still the main domaon controller. It shows its local ip and the ip that it claimed for incoming vpn connections from the DHCP server. So why do i keep connecting to the other domain controller at the remote site when i go into AD?

Have you setup the subnets in AD Sites and Services? That is what AD uses to determine what DC the client should be using by default.

Cheers,

i had that setup before i re-did everything when i installed exchange and i couldnt get it to work right. it kept having sync errors so i just put them back on the default subnet and it worked perfectly. Before i reinstalled everything from scratch i didnt have this problem.
