Linux and Windows Remote Desktop
A nice and convenient variant to use RDP from a Linux box to a windowos system is xfreerdp.
The following switches are used to enable multimonitor usage as well as microphone and sound. Monitor 0 and 1 is used in full screen mode on the linux box.
xfreerdp /monitors:0,1 /multimon /sound /microphone /u:<user name> /v:<ip address or domain name of the server>
