NT4 clients registering in W2k3 Active Directory

I have an NT4 domain that I am migrating over to Active Directory. A pdc and a bdc. Once I do an upgrade of the pdc to server 2003 and then run dcpromo to install Active directory i was wondering when do the computer clients logging into the old nt4 domain register themselves in DNS in Active directory's namespace. I have not upgrading the bdc yet because of an exchange 5.5 migration to exchange 2003 that needs to take place, so the functional level is still mixed mode. I see all the user accounts and computer accounts in Active Directory Users and Computers snapin, but i see nothing in the dns snapin on the upgraded domain controller that now holds the pdc emulator role. I'm guessing that i have to add the old nt4 dns/dhcp box to Active Directory or something.

Any ideas would help...thanks

NT4 Clients can join an Active Directory, but you may need to use the DHCP server to register their DNS entries for them. Look in the properties of the DHCP server in the DHCP snapin. The DHCP server is capable of registering clients in the DNS that cannot do it themselves.

Also check that the DNS settings on the clients are set to "register this connection in DNS", if the setting is available.

The thing is that I am doing an inplace upgrade and do not want to have to touch any of my 800 or so desktops. They are all on dhcp and since they get all their pertinent info from the dhcp server like dns servers, shouldn't i just upgrade the dhcp server to be a member server in Active Directory. The dhcp server runs dns also so its the same box.

If the DHCP server doesn't have the ability to register clients in DNS on their behalf (as it wont have under NT4) then you will have to upgrade the DHCP server as well to Windows 2000 or 2003.

Thanks...

And on the note of the dhcp member server in the nt4 domain, is that just upgrading the OS to benefit from 2000/2003 servers dhcp and dns options.

Now after upgrading the OS, do i add it to the Active Directory namespace or what so it will know about the new namespace to register in, which is actually the same domain name as the nt4 domain, I just added the dot com because of AD's FQDN operation.

yup, there is nothing else that will cause you a problem with DHCP. You will need to revisit your backup for DHCP and be aware that it will need to be authorised on the domain before it starts giving out addresses - once it's joined to the domain.

So, yes, upgrade your DHCP, join it to the domain and autorise it on the domain. Then make sure it's DNS name is correct and set it to register clients who cannot do it themselves.
