Joining a domain

[WALKINDAKAT]

In the unattendjoin part of WSIM for Windows 7 Ent, should you put the whole domain in for example constoso.com or just contoso

and if you add an autologon section, should you put a domain in here. Also should this be added to the specialise pass and oobe pass or just one or the other?

Also some people have suggested adding a net user administrator /active:yes but if you add autologon would this not take care of this

I'm slightly confused!

Thanks for any assistance
