Just follow the steps for forestprep & domainprep and then introduce win2003 DC. It will be in same domain.
This also covers, some checks for exchange too.
Of all the services, DHCP can become risky to move without adequate safeguards, take a look at this article.
How to move a DHCP database from a computer that is running Windows NT Server 4.0, Windows 2000, or Windows Server 2003 to a computer that is running Windows Server 2003

Thanks for the advice! Excuse my ignorance, but how do I upgrade the schema, while I'm installing the WIN2K3 server? Ditto for migrating FSMOs.
Does it mean that I would have a 2K and 2K3 AD domain coexisting for a while until I remove 2K AD?
When you said move DNS, WINS, DHCP, you meant Just installing them on the new server, right?
Did you also have to migrate Exchange (from 2K to 2K3) by any chance? If so, in what sequence you did the upgrade?
Thanks

I would, if budget allows, go the second route. Do the schema upgrade bring up new windows 2003 server. Migrate FSMO roles to it. Move DNS,WINS etc to the new server and then DCPROMO, one at time, your other servers out. Reinstall them with W2K3 and dcpromo them back in. Did this with a 700 user network with no downtime.

P.S
Look out for the article on migrating your DHCP database.

Subject: [ActiveDir] AD Migration Question
I have a W2K AD that I want to migrate to W2K3 AD. What's the best option: In-place upgrade of the W2K DC or standing up a brand new W2K3 DC server
And then upgrade the W2K DC to W2K3?
By the way the W2K DC is also running DNS, DHCP, & WINS. I have one more DNS server. If I go the second route do I need to set up a DNS server or can I use the existing ones?
Thanks
