hey guys :P
i run Windows 7 rc1 x64 on this machine and i got a laptop with the same os and version but x86.
edit: it works now via passwords. when i try to connect to my external hdd from my laptop it asks for username and password and i can move files around.
weird thing is that it doesnt work from pc to laptop. it says "login failed: user doesnt have the needed login-type on this computer" or smth like that. what the f?
