I've got two pc's on a home network connected through my router. Both have got Zonealarm (free version) installed. Recently my main PC has been slow or failed to connect to the net and outlook express has not always been able to pick up my emails (message comes back could not connect to server). The second pc has been connecting fine so I unplugged it from the network in case it was getting preference. This made no difference. I turned off Zonealarm on the main PC and everything connected fine. Turned it back on and problems again. Strange thing is this doesn't happen all the time. Any ideas?
