Migrating to Windows 2003 AD 1

[HeathRamos]

I need to mirgate from Windows 2000 AD to Windows 2003 AD.

I have three main concerns: moving DNS from the Windows 2000 DC to a Windows 2003 DC, pre-Windows 2000 desktops being able to log on and forestprep/domain for Windows 2003 (moving dhcp and wins seems simple enough).

#1 Moving DNS

How exactly do you move a active directory integrated DNS server from a Windows 2000 Server to a Windows 2003 Server? Should I do this before or after I run dcpromo on the Windows 2003 Server?

#2 pre-Windows 2000 desktops

I've read somewhere that you need to make a security policy change inorder for pre-Windows 2000 desktops to logon once you install a Windows 2003 DC. Any other issues?

#3 forestprep/domainprep

I ran forestprep and domainprep from the Windows 2003 Server cd before I installed Exchange 2003 awhile back. The servers I have now mainly run Windows 2003 R2. Do I need to run forestprep and/or domainprep again from the Windows 2003 R2 cd before attempting the dcpromo on the Windows 2003 Server?

For a Windows 2003R2 server to become a DC you need to run adprep from the 2nd 2003R2 cd.


To move DNS simply promote a 2003 box to a DC and then install the DNS service on the new DC, assuming you have AD integrated zones the new DC will pick these up automatically.

And this for how to have pre windows 2000 desktops login to a windows 2003 domain;
