Update to #22
I actually resolved the problem by reinstalling Windows 7, and - far more
important - used Win7-computer-name instead of actual Domain Name to Login.
Probably this is the hole point.
I'm not sure if under XP the Domain Name *was* the Domain Name and not
the computer-name. However
I actually managed to access the 'User home folder' in 64bit 7 ultimate,
using both Ubunutu 10.10 and 11.04 in x32.
The trick is to go there via nautilus/file/connectToServer/windosShare.
Add then the IP of win7 machine to field Server. Add win7user(which is set up
on 7machine) to field User.
