Can Windows 2000 Server work with Windows 2003 Server?

Is it possible to use Windows Server 2000 in conjunction with Windows Server 2003? What I mean is whether we can make the Windows 2000 Server machine a kind of a backup server for the network domain where we actually can also create accounts and home forms for the users? Will Windows 2003 Server acknowledge these accounts? Will the users be able to login with an account created by Windows 2000 Server?

There a couple of limitations but yes. We have a mixture of windows 2000 and windows 2003 servrs running as DC's on our domains however, we have added the 2003 servers to our 2000 system. This all works perfectly; the one caveat is that we have not raised the active directory to 2003 as yet. ie the 2003 servers participate as controllers within a windows 2000 Active Directory structure.

What about the other way around?

have you installed your windows 2003 in native mode? If yes, then no you cannot do it the other way round as your 2003 boxes will be operating with a 2003 Active Directory schema and the 2000 box will not be able to interact with it.

If I where to use another Windows 2003 Server instead of Windows 2000 Server. What should I insytall it as? The main server is the DC of a forest.

Once you add a second 2003 server to the domain, you will run dcpromo to raise its profile to be a domain controller. Once the active directory has synchronised and you have the dns running correctly etc you will be able to use this box to create and administer accounts in exactly the same way as the existing 2003 DC.
