Hi
Network Neighborhood anounces itself every 15 minutes so It aint normal network trafic most probably .

Rather check if there aint some other thing , like a florecent light or aircon thats switched on somewhere when it hapens , if the networkcable runs near any of these or any electrical cables that hgas motors or some other high Wattage devices it WILL bring down network performance and even reboot PC s .

So check that and maybe run a network monitor so that you can see where the trafic is coming from , it may just be a user coping some big files over the network ,also try upgrading to switches since it will bring down bandwith usage .

Hope something from all this solves your problem ,
and I will like to hear what worked

You had some other postings out here as well for internet problems. Get a good firewall. Apply all security patches for your operating systems. Its not a safe world out there! Good Luck

There are 2 things I check when something like this happens: 1) we have a managed switch that allows me to monitor the traffic on the ports and if I see unusual traffic on one or more ports, it is easier to track down the problem. Sometimes it is adefective noisy NIC on a PC, sometimes its someone sending large files. 2) our ISP provides us with graphic usage of bandwidth by the hour, by week or a span of weeks. By monitoring the time of high bandwidth usage, we can determine if there is a possible DOS attack, or some other issue.

Seen this when a 10/100 NIC is set for auto and it hooked up to a 10 hub, try setting the speeds on the NIC's to natch you equipment.
