Use existing or create new domain?
Need to get people's thoughts on a dilemna at work. We are running a vanilla windows 2003 domain and currently have funding available to upgrade servers. I am wondering whether or not we should be creating a new domain or just migrating the old domain over to the 2008r2 server. The old domain has problems like we can't log in on win7 or vista machines and the logon script and GPO's need a complete overhaul. But if we create a new domain it will take me months to change over the systems and get the users on the new domain.
If it was you what would you do?
