We have an XP machine that has a huge (trillions) amount of packets being sent out (to where we don't know), and only receiving a handful back. This is causing the entire workgroup (only 4 PC's) to slow down and internet browsing is affected as well. Really can't find what is being sent out or what program is doing the sending; there are no rogue processes running, and firewall and scanners show no large activity. Could this be a network adapter problem? It is on a Sony Vaio with an Intel PRO/100 VE adapter, and there are two Network Bridges that we cannot delete through normal means. Any thoughts? Thanks
