Question

Windows Server Std 2003 R2 Add to Windows Server 2000 DC with AD

Active Directory, Windows Server 2003, Domain Controller

How can I promote my new Win Server 2003 a new Domain Controller and replicate the existing Active Directory of Windows Server 2000

Hi,

Ensure the existing 2000 DC with SP4
Add the 2003 server to the 2000 domain as a member server
Copy I386 folder from 2003 server CD to 2000 server
run (from that i386 folder) adprep /forestprep ( on the server which holding schema operations master ) and adprep /domainprep ( on the server which holding infrastructure master )
run DCPromo on the 2003 server to promote to DC

But check your 2000 AD with netdiag.exe, dcdiag.exe, and replmon.exe (all from the Support Tools) before you start. Unless you get an error free result from dcdiag as well as netdiag, you basically don't need to bother with the upgrade.
