I created a user with a simple password and am able to authenticate from
only 1 machine on my network.

I have several other machines on the same subnet as the above machine but
it tells me "unknown user or incorrect password" when I try to
authenticate. I tried shutting down the machine where I could log on,
thinking that perhaps it was only allowing me to authenticate 1 user at a
time. But this was not the case.

The machine that CAN log on is an XP machine. The ones that can't logon are
both XP and W2k machines.

Any ideas why only 1 machine can authenticate via cifs and the other
machines on the same subnet receive the error message?
