I'm about to get ready to install a Windows 2008 server into a 2003 mixed mode domain, making it a domain controller as soon as I can. I know I have to run (the 32 bit versions) of adprep for forest and domain on the current domain controller. My question is, will this take the domain down for users while the changes are being made? Can they still work in their files while it is running?
There are about 20 workstations on the network. Also 3 servers are running, two already domain controllers. The two DCs are old and rather bad shape, and want to get this new server in pronto.
Anyway, I believe I have all the step by step instructions, but just not clear if adprep will stall out the network and users will be forced to sign off.
