Configuring DNS on a branch office DC not working
Posted on 2008-10-08
Firstly, yes, I have read a few other threads on this issue but I am still having issues and hoped for direct help.
I need to prepare a DC for a branch office, about 50 users, over in Europe. We are a US based company with 125 users.
Issue: I created a new DC in a new subnet for the branch office. DNS does not import the AD DNS information for forward lookup zones. It only shows the reverse lookup zones. When I create a new DC on my own network and install DNS it usually has all DNS information already populated from the AD.
Config: Main site: 2 DC's running WIndows 2003 Server w/ AD integrated DNS. 192.168.200.x network.
New site: DC is built as a VMware virtual machines on ESX 3.5. 172.20.20.x network. Cheap home router being used to interlink both networks until new Checkpoint firewalls arrive.
Here's what I have done so far:
1, created a new Site in the AD.
2, I created a new subnet of 172.20.20.0/24 in the Sites container.
3, in the Inter-Sites Transport I modified the DEFAULTIPSITELINK to include both sites
4, built a 2003 server on my ESX 3.5 server. IP address 172.20.20.7
5, configured a 2nd IP address in the 172.20.20.x net on the nic for my main site DC(192.168.200.7). Why? This was needed to allow bidirectional communication since I am using a cheap home router. This allowed my main site DC to ping the new DC in a different subnet. I verified both servers could ping each other before continuing.
6, installed DNS, WINS and DHCP on new server that will become DC for new site.
7, DCPromo'ed new server(172.20.20.7) to become new DC for new site
When I open DNS, all that shows is the reverse lookup zones. If I try to create a zone with the same name it tells me that there is already a zone with that name.
After a few hours of troubleshooting, I gave up and DCpromoed the box back down to a server and tried again with same results.
1st, Is a single domain with 2 sites the correct path to go down to minimize site to site traffic? (we will have 4mb connection and they have 2mb)
2nd, If yes, am I going about configuring DNS the correct way? Should I see all DNS information show up on my new DC and something just is not working correctly OR is this the way it works if a DC is in another subnet and I have to configure that site manually?????
