We have an ISA 2000 array and one of the developers has a script that he is testing on his machine which basically connects to a website to down download some files. He has specified the IP/Port of the proxy in the script, but for some reason it wont go through.
If he takes the proxy ip/port out of the script, we can see the machine trying to access the internet as its hitting the corporate firewall, but the firewall is blocking it as it will only accept this type of traffic (https) via the proxy server.
So the proxy itself is stopping his machine connecting via the script. His normal internet access is fine and the proxy has the appropriate port opened up to handle port 443 traffic.
All i can think is that maybe the proxy is asking for authentication, however he doesnt know how to enter this into the script.
Is there a way on ISA we can monitor the connection coming in from the client machine or maybe shut off authentication from that specified machine so that it can go straight through? Im new to ISA by the way ;)
