Long ago in 2007, I saw a M$ article that describes that Vista has an extremely short delay period to get an IP. If it doesn't get it within 1 second, it gives up (and maybe tries again). Common DHCP servers ping an IP address, wait 1 second for a reply, and if no reply, assumes the IP is available and leases it to the booting computer.
This one-second delay might be causing Vista to time out. The article explained how to lengthen the timeout, but I'm going to direct your attention to another vector. Is your DHCP server authoritative? That means, that no matter if any other DHCP servers are on the network, the authoritative DHCP will butt in and force/offer it's lease in preference over any other DHCP traffic on the network. The other question is why you have it as a bridge, when sysctl net.inet.ip.forwarding=1 might all you need. Another Q is why you might have a DHCP server listen on one IP (let's say it's the wired interface), but not on the wifi (this wasn't clear in the OP, but it might be the case).
