Our company virus scanner (Sophos) was auto updating itself yesterday with a large monthly update. We have the network bandwidth throttled to 100k reduce the overall load on our network but as the process was updating, all the computers hung because they couldn't access the network shares etc. The system idle process was running at 98% so to me it looked like the virus scanning process was hogging the Ethernet card. Shouldn't windows process scheduling prevent a single process hogging the network card or and is there another explanation for this behaviour?
Many thanks, Richard
