Apologies for this, as I know this has probably been covered multiple times. I have read everywhere, but cannot get this to work. Here's the set up: I have a WD MyBook connected to my new Win7 notebook. I right clicked on the drive and selected advanced sharing. I called the shared name 'Media' and allowed 'everyone' 'full access'. I can see this folder (the external HD shared name 'Media') from my XP machine, but for some reason I can't access it. Here's the prob. I could access the external HD connected to the Win7 machine when it was in its original FAT32 state, but I formatted it this morning to NTFS (so I could put larger movie files on it). I set it up the same, but as I said - I can now only see the external HD connected to the Win7 machine from my XP machine, but it won't let me access it. I get the standard '... you do not have permission to access this network resource' error. I have spent 4+ hours trying to resolve this, so any help would be much appreciated.
