Having difficulty with a homegroup and file sharing: one desktop PC with the family's main documents (which are on a separate drive to the system) and two laptops which need to access those documents. I've got them all seeing each other, and they can see the folders in the drive, but when I try to add files or rename files, it tells me that I need permission.
I've gone through the advance settings to make sure the correct permission is selected, they all have the same workgroup name and different computer names. Sharing the printer attached to the desktop is fine.
What else do I need to do?
