I'm using VTune 7.2 running the client on XP Pro SP2. I installed the remote client on a W2K as well as an XP machine. I'm able to get a sampling from the XP machine, but the W2K machine doesn't seem to do anything. I launch the activity and in a few seconds VTune is back to normally as if I didn't do anything - no messages, no warnings about missing samples, etc. Any ideas?
