I have just tried Rdesktop 1.7-maemo3 but does not seems to work for me. Some more info:

1. VNC is working on my N900
2. I enter my local IP address, my windows 7 (64bit) username and password
3. My "Allow remote assistance connections to this computer" is checked in Win7
4. My error message with GUI version: "RDesktop cannot connect"
5. My error message with command line version:
EINPROGRESS in connect() - selecting
Timeout in select() - Cancelling!
6. Connecting both my phone and laptop via WIFI
7. I leave domain field empty...
8. I'm using the very latest maemo: 3.2010.02-8.203-1

Can you please help me? :-)

Tried rdesktop-cli 1.6.3 but got the same error message.
Do I need further windows 7 or router configuration? (VNC works, I am using UltraVNC on windows)
