Question : Windows 2003 A.D. integrated DNS - nslookup timeout errors

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?

Error:

DNS request timed out.
      time out was 2 seconds

Thanks for the assistance!

Answer : Windows 2003 A.D. integrated DNS - nslookup timeout errors

You can prevent this from going out to the internet on domain.com searches...by adding a forward lookup zone called domain.com

Once you do this, your internal DNS servers will not try to forward to the internet on either corp.domain.com or domain.com.

you will have to manaually add any records (like for you external website) on your internal Windows DNs server in the zone domain.com.
