samba - Oct 2005 - WINS 1c query, many responses: who is chosen?

Scenario (everything samba-3):
- many subnets, each with a BDC
- one PDC somewhere else
- one WINS at that PDC server
- windows using wins first, bcast next (node-type 8)

When one workstation asks the wins server about the <1c> netbios name
type, the server will answer with the PDC and BDCs IP. What prevents the
workstation from using a controller outside its subnet? Is this
"intelligence" part of the windows workstation DC selection algorithm?
To choose the closest one?

Yes.  The DC selection heuristic is built in to the
windows client.  The client also uses the GETDC mailslots
for selecting DC's.
