Network Setup?

Network setup now:

3 Windows 2000 DC
1 Exchange 2000 - 2000 box

Upgraded Network:

We want to upgrade one of our 2000 DC to 2003....Then replace one of the 2000 DC with a new 2003 DC server....

My question is do I need to also upgrade the last 2000 DC to 2003 to work on the network?  Will it be easier just to upgrade it?  Or can we just leave it as a 2000 DC?

Also will there be any problems with leaving exchange 2000 on a 2000 box in a 2003 domain?

What steps do I need to make sure everything will work?

Thanks

There are 4 modes with 2003 that you can operate in:

Mixed (NT and 2003)
Native (2000 and 2003)
Windows Server 2003 interim mode
Windows 2003 Mode

Windows Server 2003 mode only supports Windows Server 2003 domains, so it's a choice only when you're building a new domain with Windows Server 2003 only, or when all DCs in an existing domain have been upgraded to Windows Server 2003. Because Windows Server 2003 mode only supports Windows Server 2003 domain controllers, you cannot introduce DCs running earlier versions of Windows Server (including 2000) into the domain forest after elevating the forest functional level to Windows Server 2003 mode.

Regardless, the answer to your question is to leave the DCs in Native Mode, and you can run your domain without upgrading all servers...  Of course, this has to do with your DCs only...

If I left one of the servers 2000 and operate in native mode will I lose functions that come with 2003.....group policies?

No...  As long as you are running a 2K+ domain, you will have full functionality over Group Policy and ADUC...  I run a mixture right now of 2K3 and 2K..  no problems whatsoever...  :)

Windows 2000 Sever native mode eliminates the restrictions imposed by Windows NT compatibility. Unlike mixed mode, native mode supports universal groups, nested groups, conversion between security and distribution groups, and SID history (to allow migration of security principals from one domain to another). Moving to native mode disables NT domain controller emulation, however, removing the capability for replication with Windows NT domain controllers. In addition, Windows clients earlier than Windows 2000 must use the add-on Active Directory client software to enable interaction with the Active Directory.

Moving up to native mode also provides for greater security because you can switch to Kerberos for authentication of Windows 2000 or later clients. Earlier clients can continue to use NTLM for authentication, although NTLM results in decreased security. Finally, Windows 2000 Server native mode improves domain replication by moving away from the PDC/BDC topology imposed by Windows NT to the multimaster replication topology offered by Windows 2000 and Windows 2003.

Windows 2000 Server native mode is the choice to make when your Windows Server 2003 domain controllers must function within an existing Windows 2000 domain or when Windows 2000 DCs will be introduced into the Windows 2003 domain, if only temporarily. Using native mode ensures that the Windows 2000 DCs can interoperate with the Windows Server 2003 DCs in the domain.
