Nor can I access either PC from the other. One other weird effect is that during the course of Wednesday night's event, I got several requests to reconnect popping up on the old machine. Odd, since it was still running both Thunderbird and Servinfo. Narrowing it down a bit, if I then tried to access Yahoo it did so immediately but when I tried to access the GoFlight site I could only do it if I did press the reconnect button. This network lark has opened up a whole new area. Like a Black Hole is an "area". Gerry, I got something similar recently, I found somehow my XP Firewall which had been off for ages (since the router arrived) suddenly came on again and started blocking network traffic. I've now told it that its ok to allow access from the internal network, this cured the problem, but now every time I switch on I get a warning message, which is a pain. Frank T.
