Recently Migrated to Active Directory-Some computers showing fully qualified domain name, some not

I've recently Migrated to AD. I've noticed when looking at my new dhcp server, only some computers show the fully qualified domain name in the computer name. I've noticed a coorolation between the computers that do not have the fqd name also dont reflect the correct time from the new win2k operations master. The strange thing is that they are pulling their ip's from the same dhcp server. Are these machines still authenticating off an NT DC?

Also, I need to move dhcp to a new server. Is it ok to set up the new scopes on the new server, and deactivate the scopes on the old server?

Quick note: I just noticed that the "dns suffix for this connection" in the dns settings for the operations master domain controller(the box that I performed the upgrade on from nt to 2k) was still the regular domain name. I just changed it to the fully qualified domain name.

Its gets worse. I couldn't do an operations master role if I wanted to because it tells me the current operations master is offline. The server its referring to is the original machine that I upgraded and it still shows the non fully qualified domain suffix. When I look at the server itself, under network identification-it DOES have the new fully qualified domain name.

First, yes u can move dhcp to another server.  You can actually migrate exactly what you have to the other server.

ive done it many times and it saves alot of work, at least to me.

Second, make sure wins is installed and the IP address included in DHCP and your clients are set to receive all ip settings.  In DHCP u can also identify your time server.

What u may want to do is force a the other dc to take over the operations master roles, then rebuild the other machine.  Make sure to NOT bring that dc back online after you do the seizure, if you choose to do so.
