License Borrowing Not Working

We have one laptop user who suddenly can't seem to borrow a Revit Series 7
license. When connected to the network, he can borrow a license from the
license manager no problem. But when he disconnects, and tries to open
AutoCAD or Revit, he gets the "Specify License Server" dialog box. After
this, we reconnect him back to the network and when he opens one of the
programs, he is reminded that he's using a borrowed license. Weird.

All other laptop users are functioning normally, so this doesn't appear to
be a license manager issue. Rather, it appears to be related to this
specific laptop or user. I can't find anything out of the ordinary, and have
even reinstalled the programs in hopes of resolving this issue.

Any help greatly appreciated.
Thanks...

Does he have the same network interface card both when connected and
disconnected? There have been reports of problems with users who have NICs
in their docks at work, but not when disconnected from the net.
