Upgrading from Server 2000 AD to server 2008 R2

[LiliMike]

I am confused with the results I am getting so I am hoping someone can clarify what I've missed.
Presently installed is Server 2000 as Domain controller only serving files / DNS.

I want to setup a new server with 2008 R2 which will replace the old server.

I made sure server 2k had SP4 and running in native mode
Using the 2k8 R2 media I ran on the old server:
adprep32 /forestprep
adprep32 /domainprep

Then I installed 2k8 with basic and added it to the domain as a member and pointed to the old server for DNS

ran dcpromo on win2k8
disable Global catalog on 2k

transfer the 5 FSMO by running ntdsutil in this order:

Type "roles"
Type "connections"
Type "connect to server mnserv3"
type "q"
Type "transfer schema master"
Type "transfer naming master"
Type "transfer rid master"
Type "transfer pdc"
Type "transfer infrastructure master"
type "q"
type "q"

transfered all DNS zones and insured config was identical.

At this point I had an XP PC running shared files on the old server and was able to move the shared files to the new server, modify the login script to point to the new server, reapplied the user rights to access the files and all was good.

Then I shutdown win2k

And XP PC can no longer see the 2k8 server even if I turn back on 2k.

I remove the PC from the domain, rebooted, re-added back to the domain, surprisingly profile was maintained and all was working.

Then I ran dcpromo on 2k to remove it completely and shutdown.

PC is still working well with shares.

This was a test environment but if I can avoid removing and re-adding all PCs from domain I would save a great deal of time.

I established my procedure based on the instructions found on a forum but I could not understand the following, I was wondering if that was what I did when I used ntdsutil or if this is something different:

(manually Check Replication Topology and afterward manually trigger replication to synchronize Active Directory database between 2 replica.)

Any help would be appreciated.

Based on your steps you outlined, when you first turned off the 2K box, no where did you say you added the 2008 R2 box as a Global Catalog and nowhere did you say you dcpromo'd the 2K box to remove AD (until after your "problem"). So at that point in time, you had a AD that had no Global Catalog(GC) server, was missing the domain controller that AD referenced as the only GC, so yes... things probably did not work well for you. You didn't have to remove computer from domain and rejoin, you just needed to remove AD from 2K box, after moving your FSMO roles, DNS was synch'd, repointing servers DNS and clients DNS to the 2008 box, and making 2008 box a GC. Letting all that settle down, then remove AD off the 2K box with dcpromo. Give that a little time, and check DNS properties to make sure any references of DNS servers do not include the 2K box (unless you are leaving it a DNS server for some reason).

Disclaimer.... I'm on meds right now, so someone better check my logic.

Go through my faq1674-7371.

There is absolutely no reason to have to re-add PCs. Ever.

Cajun,
After I ran dcpromo on the new server I verified the Global Catalog and it was already activated. At that point I de-activated the old server Global Catalogue.
Maybe I just shutdown the old server too soon?

58,
Thanks for the link, you have just defined my schedule for tomorrow.

Thank you both for the replies.

If you were running Windows 2000 you also need to do
adprep32 /domainprep /gpprep

How soon did you do this? You need to allow a little time to ensure that AD replicates completely.
