I am migrating a novell 5.1 network to Server 2008 R2. I have the luxury of setting up the new server and testing it, tweaking, without going live until I know everything is working. I've set up active directory, DNS, etc. My first XP machine logged into the new server without problem except that it created a new user on the client. (I now have Scott (old user name) and scott.ids (new user name) under documents and settings on my XP machine. Our machines are 90% XP and a few new computers with Windows 7. I didn't realize this would be the case, I assumed I could use the employees current user name on their computer. Is there a way to make this happen? Otherwise, each machine that connects to the new Domain server has to create a new user account on the clients machine? I would then have to migrate all data from their old user account to the new one? I have a very simple network. The server will function as DNS, File Server, and we may at a later date migrate a SQL database to the box. Is there a setting in Active Directory that allows me to use the current clients user name?
