Almost there but not quite so simple, previously (1.9.16 and below) samba
would connect to the password server as under the name of the client on the
samba server. This caused the the NT server to kill any connections it had
to the client since as far as NT is concerned a machine can't have 2 IP
addresses so the other must be a ghost. This was changed in 1.9.17 to
instead identify itself as a combination of the remote machine's netbios
name and the PID of the smbd process attempting to authenticate. This was
considered the lesser of 2 evils since you can turn the errors off by
removing station restrictions, but you can't remove the dropping of
connections problem.

There's more info on this, and a workaround if you want to go back to the
old method in an email posted a week or so ago titled "access problems for
restricted clients"
