Kuddos to you, you are somehow correct.  I plugged the affected laptop 
directly into the dhcp server interface, and wallah, got an address. 
Wasn't making sense to me since it was all L2, and, the other dhcp
worked fine with this laptop, going through the same router.  Now just 
have to figure out "what" on the network is doing this and how.  Thanks
everyone for their time!
