I assumed when you configured squid you also adjusted the proxy/firewall
rules (iptables?).  You need to make sure those permit access.  On a
client you should be able to "telnet www.yahoo.com 80" and get a
connection when squid is not running.

More or less, but modern browsers do other things unfortunately.  I
believe NT, etc... has either the nslookup or host command line
utility.  Use that to verify DNS operation.

Sure, DNS always does.  Does IpCop support a caching name server?  If
so, enable that and point clients at the IpCop box itself for DNS.
