When ever I try to download extensions from behind our ISA server it fails. If i plug the same machine directly into the web there is no issue. I have tried using the firewall client with no joy. I have http and https opne on the firewall and I have even added a access rule for all traffic from the laptop but still no luck. When I run a trace on the ISA server the only error I see is:-
A connection was abortively closed after one of the peers sent a RST segment.
But even this is not denied in anyway. Thanks for any help.
