i just got one from ebay lately and ive been trying to set it up for 2 days not and still i cant make it to work like i want to.
my setting is just a volume1 with all my media files in there. 
basically it just like this:
Volume_1 
   -iceman
   -itunes (my itunes library)
   -movies
   -tv series   
all i want to do is to restrict others for manipulating my data over the network. so waht i did is put a userA and put the Volume_1 and all the subfolder with a read/write permission on.

then i went to network shares and put the volume_1 and set the permission with read/write only to userA and the subfolders with just read access. 

now the problem is when i access the itunes folder inside the volume _1 folder and try to write on it i got this error

then i put my user password and then i got this

it so simple and yet its making me miserable. i cant make it to work....  
 
  
 
need help
