Remotely adding a machine to a domain

[henry isham]

Hi all,
 
Is there a way to remotely add a machine into a domain? I have all the necessary id's 
and passwords (admin on the domain, and admin on the remote machine). I'm just trying 
to save my self a trip to a whole bunch of machines. I've already looked at 
Win32:NetAdmin and Win32:Lanman, but nothing jumped out at me. 
Any hints would be greatly appreciated. Thanks.
