I am setting up a brand new DC for a new Forrest at a corporate headquarters. I will be eventually putting in an SQL Server and an Exchange server. What domain name should I use for this primary DC. I want to make sure everything resovles properly after I get DNS and Active directory in place.
I set up DCs before on smaller implenmentations, and I am just starting to take my upgrade for my Winnt MCSE, but I don't want to foul this up. Some had told me to just use the domain name of my company, and other told me this was wrong.
What is best practive? If I own the Internet domain name "xyz.com", do I create my domain in DNS as "xyz.com" in active directory, or should I use a different name. Should I use hq.xyz.com, or use something completely different like hq.xyz? This site will always be the primary site for AD.
