I have set all groups, users, etc. will all allow permissions. I have 2 computers - one laptop one desktop using windows 7. Laptop has Home Premium and desktop has Ultimate. I can access and alter/edit files when I am on the desktop and accessing the laptop. I can access but cannot alter/edit the files when on the laptop accessing the desktop. I would like to be able to edit files when I'm on laptop and accessing the desktop. Laptop is wireless and desktop is wired. They are both on the same Homegroup. I have beat this to death and have run out of ideas. Can anyone help with this issue?
