NTto Server 2003 upgrade

What kind of error do they get when trying to log on? You can't log on directly to a domain from a workstation that is not a member of the domain, unless your workstations are Win9x, in which case domain membership is moot and it should work fine. For Win2K/XP workstations, when the computer is joined to the domain, a SID is assigned to the computer, and a trust relationship is created between the computer and the domain, and that is missing in your scenario. The old SIDs from the NT domain will not work on your new AD domain - the workstation has to be rejoined even if the domain name is the same.

You could have the users log on locally to the workstation and then access the domain through Network Places. The first time they try to open a domain resource, they will get a logon request at that time. Then, once their credentials are established for that session, they probably will not have to log on again until they log off or reboot.

Hope this helps!

Here are a couple of things that may prove useful the first is the Migration from NT4 to 2003 Tool Kit

And this is the recommended method of Migrating a NT4 Domain to a 2003 Domain

Hope that is of some help.

Turns out DHCP was incorrect. I tried assigning new DC as static DNS server and all worked. Spoke to tech who manages DHCP server and had scope recreated and all worked.
The SIDs were migrated during the upgrade. Thank you both for your suggestions.
