Those of you out there with relatively large domains can understand what a pain it is to search through AD Sites and Services to find which site a domain controller belongs to.
Being that I am very impatient I decided enough was enough and figured out how to use a tool called nltest. It can do all sorts of things, but for now check this out:
nltest /server:<servername> /dsgetsite
Not only can you run this against a DC, you can run it against any computer in your domain to find which site it belongs to.
