You can easily access your Windows computer desktop from a Linux computer with the tool rdesktop:

[bash]rdesktop -u username -d domainname -k no -f -z -p- host[/bash]

where

-k no
specify that the keyboard is norwegian

-z
to compress

-p-
prompt for password before connecting

-f
full screen (to quit full screen press CTRL-ALT-ENTER)

host
is either the hostname or IP adresse of your windows computer.

Here is a screen shot of my Linux mint desktop, with a rdesktop (without the full screen option -f) to my Windows computer at work:
