Migrating NT4 to 2003 & DNS

We are currently running 2 NT4 Servers on Domain1

NT4 PDC is
Is running WINS and DHCP w/ address pool of to
NT4 BDC is
Is running Exchange 5.5

Now I have one Windows 2003 Domain Controller that is on Domain2 with a IP address of
It is running DNS and DHCP w/ address pool of to

I have setup trusts between the two domains and they seem to be working fine.

My plan is to install EXCHANGE 2003 on this machine.

I don't think I have DNS working correctly on Domain2.

All of our workstations on Domain1 are just given IP addresses of our ISP DNS servers.

And when I'm at a logon screen at my workstation I try to logon to Domain2 and it takes awhile before it logs on.

So my main question is how to tackle DNS and should I install WINS on Domain2

If you don't run Windows NT or Windows 9x on Domain2 then you don't need WINS - but since you still have Windows NT on the network it would be sensible to install it until you're finished with NT.

You should install DNS, and point all clients at the internal DNS server (rather than the ISPs) on Domain2 so all your clients can log on (Active Directory relies on DNS).

Oops sorry.. you already have DNS installed, just a matter of giving the clients the address then. Your internal DNS should be able to (recursively) resolve external addresses.

If you have any problems with it please post again :)
Once DNS is installed, enter your ISP DNS servers as Forwarders in the server properties using the DNS administrative tool snap-in. Then your clients will still be able to lookup external/Internet addresses once they are pointed at the new server as Chris-Dent suggests.
