My computer -> Properties -> System properties -> Comupter Name -> Change Domain

For exmaple, you are in a Company, after you install a new OS, you need to set the correct domain of your company. You add it form here, then restart your machine.

After you restart your machine, you need to add your comany account into administor account.
Go to Control panel -> account -> add account

Then you can switch user. Logout, and login use your company username and password
