This new client, a veterinary hospital, already bought and built a server himself and has now called me in to help him with it. Silly humans. He created a .com domain for the Windows internal domain. In fact, he made it the exact same .com domain as his company's public website domain. I normally build servers with a .local internal domain for security and functional reasons. My gut is telling me I should simply re-build this server rather than try to re-create the domain it was built with. Anyone gone through this nightmare yet and have sound advice as to whether or not I can safely re-name the domain without having to ree-build the server? Thanks.
