And what is difficult in remote assistance the link above? Create a shortcut for the command msra.exe /offerRA and all. If you encounter problems, ask for the name or ip address (I have for quick access using BgInfo all this is displayed on the Desk) and asked a couple of times in the affirmative answer questions about allowing connections and taking control for themselves (like even there are some tweaks to do queries without connect). Profit.
P. S. a Little hasty with the answer. You need to connect to a local network or over the Internet? If the latter, then Yes, you need more action (plus the ip must be "white" to be).
