Scenario: I have mail.xyz.com, www.xyz.com, host.xyz.com as A records in my zone files. Very sporadically I get a call from someone saying that they cannot get to www.xyz.com. I have them ping around and they can ping mail and host, but www comes back with unknown host. If I have them do an nslookup and change to another DNS server out on the net, it works. A short while later the problem will resolve itself. The system running DNS is a little Pentium 75 and has 64mb ram. I do not have it doing anything else except DNS. I don't think the performance of the machine is causing the problem, but am not sure. There are no errors in the logs to indicate what the problem might be. Any clues?
