There are four or 5 computers connected to a modem , the connection speed is like 400kbs, and there is one user that is always downloading videos and music while we are working, and on top of that all the nortons are always updating, so sometimes we ARE REALLY BUSY and the connections gets worse than dialup.. I tried system manager 1.18. but it didnt work..can I disable the downloads on windows? What do you recommend?
