|It's been a long, long time since my NT 4 days but I think you might be missing a few things. I believe there are only 2 ways to migrate your NT4 domain. One is to create a new 2003 domain from scratch and create a trust between the two. Not entirely painless to say the least. |
The other way that would be much simpler, is to upgrade your NT PDC to Windows 2003. This means doing an in place upgrade of your NT server. This assumes the hardware will support 2003.
You can not just 'prep' and NT domain and install a 2003 domain controller. I'm afraid it isn't that simple. An NT domain and a Active Directory domain are apples and oranges.
The bottom line - unless you really have some ties to that old NT domain, I think you are better off just starting over. I think you'll be better off in the long run.
Good luck but do your research. Like I said, moving from NT4 to 2008 domain is a multi step process and not something for a new admin to try in my opinion.
