Windows 2012 R2 and I will be using this server as a Session Host server in a farm.
I have tested this out and have found out the error occurs as soon as I join the server to the domain.
Our Domain is at the functional level 2008 because I have one more DC that isn't 2012.
all works well and I can use the server as normal but as soon as I add the server to the domain I then start receiving the message 'windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item.
This happens for test user accounts (after RDHS role has been added) that try to use explorer.exe and some other items. It also appears when a domain administrator uses the search function (as soon as added to the domain) at the start menu and searches for 'windows updates' and then clicks on the search result, error appears. but if you go to the control panel then the function works correctly.
