What hata has suggested will mount your remote xp share to your local VL system. By 'mount' I just mean it will create a direct link to that network share so that you can access the data. Once you've successfully mounted the remote XP share you will be able to 'access XP' via the location where you mounted the share. Your mount point (i.e. location) is indicated by the '/mnt/xxx' location. I would suggest you either: 1) use the /mnt/win directory, 2) use the /mnt/tmp directory, or 3) create a new directory in /mnt and use that directory. For simplicities sake, try just using '/mnt/win' since it already exists and is a somewhat logical location to use.
By the way, you will need to adjust #2 to meet your network topography.
//ntserver = will be your actual XP computer name (e.g. //Gekky29_XP)
/download = will be an actual share on your XP computer (e.g. C_Drive)
username = will be a valid username on your XP computer
password = will be the password for the username above
/mnt/xxx = will be the actual location to mount your XP share (e.g. /mnt/win)
Example) mount -t cifs //Gekky29_XP/C_Drive -o username=XPuser,password=XPpass /mnt/win
If the mount is successful then you should be able to browse the mount point and see your XP data (ls -al /mnt/win).
