I have to rebuild the entire domain of a company I just started with. It currently runs SBS2003 but it is "FUBAR". MMC is not working, I cant use the BPA on it. I cant get adprep to work to do the prepping on this server. This server was basically setup to manage e-mail and access control. We have moved our mail services to a 3party vendor and the only services needed on this server is AD, dhcp and file access. I removed around 80000 viruses from this server and since then its just hangs and gives problems. I cant even reinstall .net framework apps. This server needs to go. I have purchased a new server and installed Server 2008 R2 SP1. What can be done and how difficult will it be to rebuild the Domain and AD from scratch. It is not a big company and they have had enough as well.
How do I plan for the rebuild. Everything was done without planning and everything needs to be done from scratch. If I switch off the DC, can I create one from scratch? Will it be possible? Do I need to take everyone off the current domain? The domain name needs to stay the same. How can I do this right the first time?
