I'm in the process of configuring 2 new domain controllers running Windows 2003 to replace our existing DC's. The DC's will run Active Directory, DNS, WINS and DHCP. I configured DNS as Active Directory integrated. Both 2003 servers are plugged into a switch. When I connect a laptop to the switch and test DNS there is a delay. I use nslookup on the laptop and set the type to any. When I type in the domain name I get the error "DNS request timed out. time out was 2 seconds" then the information appears on the screen. AD is replicating correctly and there are no errors in the event log. I have no clue why there is a timeout error when using nslookup. Forward and reverse entries are configured. The DC's are not connected to the Internet. I have to install the new DC's on Saturday and I'm worried that there is a DNS related problem that is going to effect the network.
I'm stumped. Any idea why I'm getting time outs when the only devices connected to the switch are a laptop and two DC's?
DNS request timed out.
time out was 2 seconds
Thanks for the assistance!
