[Samba] VPN/WAN Domain members

[ray klassen]

I have about 60 PC's running windows XP behind vpn routers in different 
locations. I find that they lose connection or sync (or whatever the right word 
is) to the domain periodically, probably when the vpn shuts down due to low 
demand. The result is that any domain user not already in the local password 
hash cache cannot log in and any local share with domain permissions on it will 
not allow the a domain account access if the pc is not rebooted. Is there any 
way to force windows to resync without a reboot or to make XP more fault 
tolerant to slower connections to the samba domain?

Thanks in advance. etc...
