We have the same problem with WINS registrations disappearing here. We do
have redundant WINS servers and we do have replication between them and yet
we still have this problem.

Browsing is definitely not the issue for us, the problem is that the WINS
registration disappears. We solved the problem by setting up static WINS
registrations for all of our samba servers, but it would be nicer if samba
could handle this in the same way that NT does.
