If you do not like that newly created computers in Active Directory goes into the folder Computers, you can change this with the command redircmp
http://technet.microsoft.com/en-us/library/cc770619(v=ws.10).aspx
First create the desired OU in Active Directory where you want your computers to go, here MyComputers:
Then change the default location to this new OU:
redircmp ou=MyComputers,dc=gt,dc=local
Now new computer domain members will go to this folder by default unless you specify another path on the domain join.
