I read through first, but didn't see this specifically.
I was worried about network access to my NAS, and right-clicked Security. I removed "Everyone" from the permissions, only
\\server\admin remained. Since I'm the admin and only account locally, at first I didn't catch that this user was the admin for the networked device not the Windows user account. So I logged in as the admin on my PC in Windows 7, 'Access Denied' to this folder.
These permissions aren't set from the NAS security side, but from Windows. So how do I get back access to add back the Everyone group? I read about taking ownership of it, but logged in as admin to the PC when I right click on the folder no "Security" tab is available. I tried a command prompt
takeown /F \\server\media (media is the folder I need) but it returned an error.
