Actually, if there is no NetBios Name Server (WINS), all the clients will resort to broadcast (B-node) resolution (m-node, h-node) or simply fail (p-node). I'd recommend checking out the following Microsoft KB articles:
http://support.microsoft.com/default.aspx?scid=kb;en-us;102725 http://support.microsoft.com/default.aspx?scid=kb;en-us;119493 The first link describes the LMHOST file located on all Windows clients, which might be your savior here if the network is small enough (simply add the DC to the LMHOST file and reboot). The other describes Netbios naming in general. I agree with James' statement about a DC on each subnet. It really seems to help legacy Windows networks.
