Upgrading recognition

[CryptiniteDemon]

Okay, I have a few questions and hopefully I can explain it clear enough for
you guys to follow me.

Basically I'm upgrading an NT 4.0 domain to 2003. There's a PDC and a BDC.
The original domain name is something like "CW-PS-CTRL"

Now, when I upgraded, the systems to 2003 using the install disk, the domain
name became "CW-PS-CTRL.CW.com"

Basically all the computers hooked up logged into the domain fine after this
upgrade. The XP machines even renamed themselves from belonging to
CW-PS-CTRL to belonging to CW-PS-CTRL.CW.com

NoW what I did after was take the 2003 upgrades, image them and then stored
them away on similar hardware for test purposes. I then redid my machines to
go back to NT 4.0 and then had all the computers in the network join the old
domain name of CW-PS-CTRL. So they all logged in again.

Now after that I exchanged my NT boxes for the 2003 boxes that I imaged. In
other words, just a hardware swap. However, this time, the XP machines
wouldn't rename themselves to join the CW-PS-CTRL.CW.com domain like they did
when I first upgraded the domain. They wouldn't log in to the new boxes if
done this way.

Why is this? I need to know because It may be important for how my boss
wants to do things.

So you did an inplace upgrade from the NT4 or do you use ADMT? Normally the
domain name will be displayed during upgrade and you choose yes or you have
to type the name yourself. A bit strange for me that it changed itself or
did i misunderstand you?

The machines are not effected if everything goes fine during the upgrade,
like you saw.

What do you mean with redid your machines back to NT4?

Ofcourse not, because you bring them back to the old domain like you said
with the CW-PS-CTRL name. So if you now just connect them to the new domain
CW-PS-CTRL.CW.com, the DomainSID it is different. You have to add them by
hand to the new domain now.

And i do not really understand why you more or less undo your upgrade, can
you explain?

Re: Upgrading recognition

Well basically I make ghost images of everything I do, which keeps the SID
and all that stuff.

So I have images of the NT domain PDC and BDC.
And I also have images of the 2003 DCs.

Basically after an in-place upgrade to 2003, everything goes smoothly for
the transition from CW-PS-CTRL to CW-PS-CTRL.com

But then after that I put in place the NT domain. (aka reimaged the
computer) Then after that, reset all the computers in the domain to use the
nt domain name instead of the 2003 one.

Then after that, I took out the NT PDC and BDC and dropped in the 2003
images, which still have the same SID as when I upgraded them manually
because the images hold onto the SID

But the whole reason I'm undoing the upgrade is basically my boss wants to
be able to drop in some NT boxes in case our upgrade goes awry and we have to
set everything back to NT. Our operation requires that our PCs stay running
(very small windows for shut down). Things could blow up if we screw it up.
Literally. Basically we just don't have the resources to manually reset our
200+ manufacturing PCs to a domain, so we're running through every scenario
with our test hardware and seeing how things play out.

You should NEVER work with imaged DC's, especialy if you have more then one
DC, you get conflicts with replication.

How did you do it, if not rejoining the computer to the domain by hand?

Re: Upgrading recognition

Well I did that part by hand when I go back to the NT domain. And it's not
really this part I'm all that concerned about.

The part that gets me is why when I drop in the 2003 servers (after the
"downgrade") none of the computers recognize the domain.

Re: Upgrading recognition

Hello CryptiniteDemon,

After your upgrade everything will be fine but then you added the workstation
from the 2003 domain to ANOTHER domain without .com at the end. This will
create a new entry in the NT4 domain SAM for this computer. And if you then
just connect it again to the 2003 domain, the client is NOT longer known
in the 2003 domain because it's SID is not longer the same as before. Sorry,
that i can not better explain in detail.

That makes sense.

Thanks for your help
