A couple of issues here, first and foremost is this a test or
production environment. If it is a production environment then you
definitely need more than one DC. You can get a cheap machine for a
second DC but you need that other DC in case disaster hits.
You can move system/boot drive to new hardware

I still suggest having at least two DC's
Promote another server, I would stay away from Exchange because e-mail
is the lifeblood of most organizations.
I would add another drive and you can move the AD database (ntds.dit)

I hope that helps

Exchange 2k server. My DC was built on a 4 GIG drive and has very
little room for the OS (updates are impossible). I need to put my DC
OS on a larger hard drive. From what I have read it sounds like my
first move may be to set up my Exchange Server as a backup DC. Then
reinstall Win 2k server on my new hard drive. Make the new server the
primary DC. Then AD will automatically restore from the Exchange
server to the new server. Restore my data drive and I'm set. ???
Please advise.
