Are you looking to move to a brand-new domain? &nbsp;Or do you simply want to upgrade your existing domain to windows server 2003 Active Directory?<br />
<br />
If the latter, the following KB will walk you step-by-step through the process of upgrading your Active Directory schema to support 2003: <a href="http://support.microsoft.com/kb/325379" rel="ugc">http://support.microsoft.com/kb/325379</a>. Once you've prepared your existing AD for 2003, you can simply dcpromo your 3 2003 servers into the existing domain, then de-promote and retire the 2000 servers.<br />
<br />
If you're truly looking for a migration into a brand-new domain, take a look at the Active Directory Migration Tool (ADMT) - it can help you automate most of the process, including migrating end-user workstations: <a href="http://www.microsoft.com/downloads/details.aspx?FamilyId=6F86937B-533A-466D-A8E8-AFF85AD3D212&displaylang=en" rel="ugc nofollow">http://www.microsoft.com/downloads/details.aspx?FamilyId=6F86937B-533A-466D-A8E8-AFF85AD3D212&displaylang=en</a><br />

server migration

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
