We're upping our DC's to Windows Server 2003 functional level this half term, and i wanted to check 1 thing.
Our staff login to their external email/bromcom and sims learning gateway using domain\username which is a pre 2000 logon? when we step up the functional level i understand 2000 servers are no longer support, will we loose the ability to use domain\username to login? will it have to be firstname.lastname@example.org? :confused:
