now that you mention it, if I take a remopte screen shot of a Vista machine it comes back as a blank white picture. All other OS, Windows XP and 2000, works great.
Again just to clarify, I get the message "cannot ping host" when I try to connect FROM my Vista Business to any other machine on the network, Vista, XP 2000. If I use a windows XP machine and run lsremote.exe it works just fine.
