* The Vista performance/health monitor is actually pretty good, and provides a really handy ntop-like interface for seeing which service is doing what with the network (not as fine grained as I'd like, but it's a good starting point).
You are referring to the performance monitor that appears in server manager? For some reason I can't leave that monitor running on our systems, because it slows the rest of the system down to a crawl.
Lead me not into temptation... I can find it myself.
