Hi, recently we discovered that a few users both older machines and brand new with clean installs cannot browse shared files and folders. The funny thing is that they are always viewable under "My computer" but when you try to click on anyone of them including your own personal share, you receive an access denied error. The user has full rights to the share, I can see in the Group Policy that the correct policies are applied but still no go. If you restart the computer, the drives seem to work but only briefly, maybe for a few hours at the most.
We have blown away their profiles, created new ones, as well as re-joined the computer to the domain and reset the computer from the OU back to the OU, changed the name etc. Note that this is pretty new, the users have never had any issue before going back a few years.
I am trying to think of some other points to troubleshoot but i cant seem to figure it out, any thoughts?
