One common pitfall that affects people doing unusual network  
topologies like bridging between wired and wireless is whether you've  
got proxy-ARP going, which might cause the Vista box to thing the IP  
being offered to it is really in use.  Try pinging one of your IPs in  
the DHCP pool range, and see whether you're getting ARPOP_REPLYs.  If  
so, the MAC address you get ought to lead to the hardware which is  
generating proxy ARP replies.

Of course, it might just be some Vista oddity-- perhaps it doesn't  
trust your wireless network because it doesn't like the encryption  
strength or some such, but I won't try to advise you on how to  
administer Vista itself....
