More info please Do you have a central server? If so which OS; Window, Linux or other?
Does the temporary fix work? Open a terminal window su <your password> cd /etc/init.d ./networking restart At that point can the machine suddenly see the rest of the network again? Also can i confirm that only 1 machine at a time may suddenly start 'playing up' by not being able to access the network or ping or anything but that while it's playing up Windows and Linux machines are still able to access data on the machine? (or does Windows just pretend to be able to see it but gives an error message when you actually try to access shared data on it?) Also confirming that all the Ubuntu machines suffer from this at some point or other with no discernible pattern. Aside from that all i can suggest is unlikely to help but ;- 1. Pick a problematic machine at random and ensure the cables & wires are firmly in place and not worn bare somewhere the user might brush against. Check the network card is firmly in its slot (if the side panel comes off easily). 2. Upgrade a machine at random to Ubuntu 8.10, or wait 3 months to try with 9.04. A dual-boot choice with 8.04 and 8.10 might be less worrying to setup. Actually i've always had more joy with 8.04 so i seriously doubt this is the cause. The bug-reporting tool should be working properly again now. It was glitchy for a few hours on the day you posted, classic timing - i've never known that to happen before.
