Not sure if upgrading to 2003 is a big deal.
Everything i've read seems rather positive, but i thought i'd post my plan here for a peer review of sorts.
So here goes.

1 2000 domain in Native mode
4 DC's running Win2k SP3

3 DC's in Mead Office (FMSO housed here)(TS Licensing here)
1 DC in offsite office acting as a print server as well

Running 1x Exchange 2003 server (Not 2000 so no probs here).

Here's the plan:

1.) Upgrade all Domain controllers to Win 2000 SP4
2.) Forest Prep and Domain Prep on FSMO server
3.) Leave for 24 hours to make sure there are no replication issues.
4.) Install 1st Windows 2003 Svr into Head Office. (new hardware)
5.) Upgrade it to Windows 2003 SP1
6.) DC Promo it into the domain
7.) Install 2nd Windows 2003 Svr into Head Office. (new hardware)
8.) Upgrade it to Windows 2003 SP1
9.) DCPromo it into the domain
10.) Move FSMO roles onto one of the new 2003 DC's
11.) Install 2003 TS Licensing service onto new DC and install 2000 and 2003 TS Licensing CAL's
12.) Decommission or Upgrade old Windows 2000 servers
13.) Upgrade offiste DC to Windows 2003 and update printer drivers to Win 2003 versions.
14.) Change to Windows 2003 NATIVE MODE.

We have mostly Winxp and 2000 clients with the odd Win95 as well. So I think there is a new security policy setting in Windows 2003 I need to change to make sure the Win95 PC's can still log on.

My main concerns / questions.

1.) Win95 PC's - Need to change policy to allow them to still logon
2.) Will all the Windows 2000 group policies still work?
3.) Will my VB logon script still work?
4.) Will Exchange 2003 have any issues

Am I missing anything?
Will this work?
 
After upgrading to AD 2003 and moving the roles, should you also reboot exchange 2003? Noticed Exchange seemed a little slower after the upgrade...
 
bdoub1eu, is your new controller sitting on top of 64bit OS by any chance?
 
No, not using the 64 bit OS yet...

I'm not using cached exchange mode in outlook 2003 and I noticed that when I would send a message it would sit in my outbox for about 5 seconds...Small one sentence emails too...Wasn't happening before the upgrade...

Also on Monday emails began queueing up in the messages awaiting directory lookup queue..Reboot seemed to fix the issue.
