Locking local comptuer whilst view remotely.

[DanielWalters6]

A member of staff have approached me asking of a way to "lock" the computer they are using whilst viewing others.

In a classroom environment the view multiple remote computers has become a must have feature. Although a member of staff has a problem when asked for help from a pupil.

They obviously want to deal with the request of the pupil asap, so they must leave their workstation. In doing this obviously allows others to tamper with their computer.

Is there a way in which you can lock windows hyst like the WINDOWS+L command, but still view the screens that are being viewed?

(Not just lock the program, although feature may be helpfull too)
