I currently have an NT4 domain with domain name 'mydomain'. I have also installed SBS 2003 R2 with a different domain name 'newdomain.local'. The SBS server is not configured as a DC and AD is not active. I access an mission critical database, running on SQL on the SBS R2 server via the IP address from the NT4 domain. I would now like to install a Windows 2008 server as a DC with Active Directory with a different domain name, and migrate the NT4 users. Would I still be able to access the SBS 2003 R2 (with the the SQL DB) on the 'newdomain.local' domain.
