Thanks for the suggestions, Joe! On the first count, yes, the network where
the virtual IP sits has several windows machines (a couple dozen). On the
second count, I actually gave this a shot, set up Samba and turned on WINS
Proxy, then pointed the real servers at the IP of the LVS machine for WINS.
Unfortunately I got errors in the Samba logs saying that the clients need to
contact the WINS Server. This appeared to be during client registration, but
it also didn't seem to help the issue of logons any.

the realservers are on a different network and the only
intervening machine is the director. Presumably the other
windows machines are on the VIP network.

I don't know a lot about this, so this is just a mad idea.
If you set your director up to be a samba server, can this
be used to link the realservers to the rest of the machines
on the VIP network?
