[NTLUG:Discuss] Google behind a firewall

[Douglas Scott]

It wasn't the upgrade, since Windows 98 had the same problem.  The problem 
seems to have been related to the firewall.  I had tried taking the firewall 
down and testing it but I still couldn't reach google.

I finally fixed it by rebootting the firewall machine.  I've see it do 
something like this in the past, where the firewall would stop working.  But 
it usually effected all access, not just one site, and I could usually fix it 
by rerunning the firewall scripts.  I still haven't a clue just what caused 
it.
