We've got a lot of old machines at work - some that are still running Win98. (I think we've even got some original IBM PCs still active.) Those ancient boxes aren't on the network, but we have many networked Win2k machines are running and controlling other equipment and "upgrading" them to something later doesn't make sense unless there's no other choice.

We've got site licenses for SAV and McAfee so those are the default choices. We can run other stuff, but purchases would have to be justified, etc., etc.

Cheers,
Scott.
