Checking who's on your network
What do you folks use to give you an overview of who's logged on where? I know this is a perennial problem and that the nature of Windows networks has always meant it's tricky or impossible to get a 100% accurate view, but nevertheless... when we were RM CC3 we had the dreaded Management Console, but we're vanilla MS now. Any useful tool to suggest? Don't mind if it's not free, but equally don't want a fully fledged quasi-RM system - we've already got tools for pretty much everything else.
