VB help request - Change computer name

I've been given the not so greatfull task of changing the names of some 600 computers in our domain.

Instead of walking from office to office with a floppy containing a script, I want to let some scripts do the work instead.

The problem is that my VB skills are next to 0 ATM and thats why I need some help!

What I wish to accomplish:

• Collect the names of all exsisting computers and the name and group of the (last) user
  
• save it all in ONE text file (any format will do)
  
• Have the text file contain a "suggested" new name, something like usergroup-username-randomnumber
  
• Be able to run the same file in another (or same) script and use that file as an answer file for what the new names should be
  
• Have the changes be made localy and in AD
  

I this possible?

Can someone PLEEAASSSEEE help me? I REALLY don't want to make this long walkabout

thx in adv.
