Here is the scenario:
I?ve got an old NT4 PDC in place with about 600 users. This machine is very old, and will not upgrade to 2003.
I have a brand new Windows 2003 Server.
Keeping in mind I do not want to wipe this new machine and install NT4.
I need to replace the NT4 PDC with this new 2003 Server as the AD DC.
Caveats: I cannot afford any down time, I do not want to install NT4 on the new server that already has 2003 running on it
A suggestion I received and began working on:
Bring another NT4 Server on line, A spare machine, that has the hardware to handle 2003, and set it as the BDC to synchronize the user accounts, then upgrade this machine.
Now if I understand the process correctly, I will need to promote this NEW NT4 BDC to be the PDC, and then upgrade it. As 2003 wants to upgrade the PDC first
Does my original NT4 PDC automatically get demoted to BDC? in the case I encounter problems and have to back out.
My thoughts are as such:
If I can get this spare NT4 machine up and running with 2003 as the DC with AD.
Then I can add my brand new 2003 server to the domain, and promote it to DC thus replicating the accounts, and then bring the spare (which was the NT4 BDC, was promoted then upgraded) and the original NT4 off?line?
Is this totally confusing or what?
Your thought?s and suggestions are welcome and appreciated
