Hey guys I need some serious help. I run a small lab at a small school and I recently upgraded my server to 2003 (standard edition). My old server was set as a domain controller so that any of my users can log on from any where in the lab (or anywhere in the school). My new 2003 server is set as a Workgroup. How do I change it to a domain controller so it can be like my old server. If I leave the new server as workgroup, I'm going to have to change all my computers from domain to workgroup (approx 255 computers on campus). Please if you have any help, I would be forever grateful. Thanks in advance.
