Try using the NASNavigator software to find out the Linkstation's IP address, then launch a browser and try accessing that address. The default username/password is admin/password. If that works, than everything should be OK. To map the drive to a letter, Start->Run (or on Vista, Windows Key+R), then type in "\\ip_address" without quotes, where "ip_address" is the address of the Linkstation, and hit OK. Right click on share, click map network drive.
