What error does the browser return? i.e. what error is squid showing on
the browser?
You should have all the parents listed in the NEIGHBOR SELECTION ALGORITHM
SECTION. If you put "weights' on them, then squid will check them in that
order, moving on to the next parent as the timeout expires (default 2
seconds), otherwise it will seek out the fastest responder. Also make sure
you have the inside_firewall setting to "none" or something suitable, so
that squid dosen't use itself to retrieve web sites.

There is a parent timeout variable in the squid.conf file; neighbor_timeout

Same here! Only difference with me is that the NT doesn't hang, the card
does! I know this because the proxy running on the NT (Netscape) gives
back the error message that the "site is not reachable, or server may be
down.." message.
