[LUNI] Samba Networking Problems

[Fhealy at aol.com]

I have a network at a school where there is a linux box serving as a proxy server.  I have IPChains enabled to provide NAT services for the internal network.  This server is also running samba (please, no lectures on why I shouldn't be doing this).  I am not running bind on this server.  It appears that their are brief outages in the AT&T broadband cable service that are causing the samba network to go down as well, likely because of the lack of a reply to a DNS request.  Is there a solution to this other than running BIND as a caching nameserver for the internal network?
