Use tcpdump to inspect what the DNS traffic looks like. Also verify this on the DNS server (assuming you have a local DNS server). >From your description it sounds like there is a firewall problem blocking DNS access after a while. Restarting Squid may help to such problems as a new UDP port is then allocated for DNS queries. Regards Henrik
