Upgrading a W2K DC to W2K3

I'm upgrading a W2K DC to W2K3, I don't nkow if the company wants to make the new W2K3 install a DC or not. My question is 2 fold.

1. If I'm not sure if the new install will be a DC or not should I run DCPROMO to demote the box to a member server and then upgrade to W2K3?

2. If I don't run DCPROMO to demote the DC will it still remain a DC when I upgrade it to W2K3 and if I do this will I be able to demote it at a later date should they decide they don't want it to be a DC?

Hi.  Don't run dcpromo; you can do it later if they want you to demote the server.

The server will remain a DC.

Ensure you run forestprep and domainprep prior to upgrading the server.  As for the upgrade, it is so smooth that I did all of my DCs during production hours.

gpriceee, so you are basically saying if you have a windows 2000 advanced server that is a DC and you want to upgrade it to a windows 2003 enterprise then all you would do is just slap the windows 2003 server in and let it do the upgrade?  No need to do any dcpromo or forest/domain prep?

I did it as stated in the first reply and it worked great. Only issue was this: I upgraded the BIOS, NIC and Controllers to the latest and greatest version before the upgrade. During the upgrade it asked me for the NIC and Controller drivers again. NP though.

BTW: I was upgrading from W2K standard to W2K3 standard.
