Agree... i'll check the Win98 registration process with ethereal at the
server just to know it's happening or not.

Anyway, my test was:

1.-stop everything, remove wins.dat, start everything
2.-clients setups the vpn link (10.30.60.1 the first time)
3.-name appears in wins.dat (it registers ok this time)
4.-hangup de vpn connection and redial again the vpn conn (got
10.30.60.2)
5.-name keeps appearing as 10.30.60.1 in wins.dat...

So the behaviour is not well understood yet. I setup win98 with it's
groups name (wg=remotes) and name (rstation) just to make sure it does
not colide with any other groupg in the internal network (10.60.x.x/24)

vpn ips 10.30.60.x
internal net (samba server is here) 10.60.x.x
cisco l-3 switches are doing the routing between bot nets

I did but times in wins.dat remains very long, think i don't even see a
change !!!
wins.dat actual entry

"CANAIMA-II#00" 1074460723 10.60.0.32 64R

and smb.conf has
        max ttl = 180
        max wins ttl = 180
        min wins ttl = 120
