I have a simple network. 35 machines connecting to a novell 5.1 file server that we are replacing with a Server 2008 R2 machine. I have the luxury of tweaking the 2008 box and experimenting with it until we're sure it's ready to go. I've installed DNS, Active Directory and file server options. My first XP machine logged into the domain I created but then created a new user account on the Cliient (my original user name was scott and the log into the Server 2008 R2 created scott.IDS. Is there a way in Active Directory to use the existing users account name on their individual computers, without have to create a new client name on each box when they connect to the 2008 domain server for the first time? If not, am I then faced with migrating all date from their old user names to the new one created by the domain server on the employees machine? Hope this is clear.
