[Samba] Server Maps by IP but not by Name for Domain Users

We don't run the WINS service on our network.  We have no Win9x or
earlier clients.  All clients are Windows XP.

However, to answer your question this is what I get on the server when I
run the nmblookup

nmblookup admin1:
creating lame upcase table
creating lame lowcase table
querying admin1 on x.x.y.y
x.x.n.n admin1<00>

nmblookup <client name>:
creating lame upcase table
creating lame lowcase table
querying admin1 on x.x.y.y
x.x.a.a <client name><00>

nmblookup doesn't work on Windows XP.

Thanks again!
