The ZoneAlarm Support Forum has masses of comments which can be summarised as "version 5.0 is a complete disaster and you need to roll-back to version 4.5"

In my case 5.0 stopped IIS working if it used http: but allowed https: connections. It also stopped PHP mail scripts working, which 4.5 was quite happy with.


Rolling back to version 4.5 is, unfortunately, not simple.
