i am running Vista Business and have had no problems with Windows Update until today. one update would not install and the error code says i must list the windows update websites as firewall exceptions and I must allow WU to access ports 80 and 443. I read the help files and it did not say how to do this and I explored the program options and could not find anything except expert firewall rules. If the expert rules are the answer, I certainly don't know how to craft them.
Operating System:Windows Vista Business
Software Version:7.1 (Vista)
Product Name:ZoneAlarm Internet Security Suite
