I've never had a problem at my office.  I hook the laptop up to the network, 
turn it on, and it grabs an IP.  Whenever I've taken it from home to office 
without shutting down, I explicitly ifdown the interface before unplugging 
and then ifup the interface once I'm connected to the new network.

What do the logs on the NT side say?  Is it even seeing the request?  
Anything intereseting in the Linux machine's logs?

Does it work if you shut down and then boot up after plugging into the 
network at work?

Ew.  The IT guys at work know next to nothing about Linux (and I know next to 
nothing about NT), but that wasn't a problem since it just worked.  No 
tweaking or troubleshooting involved.
