Thanks very much for the reply Steve. I'll look into setting up QoS though it's not an ideal solution for me.
Can you pass on a feature request - I'd like the ability to pause this sort of activity for say, an hour at a time for all the computers in my circle. Seems reasonable to me, akin to pausing your firewall. Plus, what's the point of scheduling update activity, when the random activity causes problems? The reality is my Internet connection is a finite shared resource, and OneCare could use lesson in sharing. <grin>
Thanks again!
