Well, i'll take your suggestion now to switch to my own DNS server. But one more thing, is there a major bug in the BIND version that comes with RedHat 9? I noticed that, we cannot stop it with 'service named stop'; I had to do 'killall named'.
This isn't something I've noticed, as I never really have any need to stop named. After making any changes to the bind configuration, I just use "rndc reload" rather than stopping and starting the nameserver.
Thank you very much. How about Squid? Any suggestions on its default options tweak?
I use squid and haven't had any problems like the one you mention. I suspect the problem is not with squid.
I think it's more likely that your 100 or so Windows boxes may be doing bogus DNS lookups in your.domain.local and that could be causing the problem. Looking at the query logs should resolve whether or not that is the case.
