I have some machines with Windows XP and Thin Clients with Linux (Wyse) and with Windows XE (Init) that connect normally in the old environment with Windows 2003, Windows 2008 and Windows 2012 that not is RD Session Host (Terminal Server) but not connect to the new server with Windows 2012 RD Session Host.
I already unchecked the option "Allow connections only from computers running Desktop with Network Level Authentication" and the old computers continues not connected to the new terminal server and gives the error "Because of a security error, the client Could not connect to the terminal server" .
Besides this option is already unchecked, if I try to connect to another server than Windows 2012 (eg the domain controller), the client connects without problems.
Any sugestions?
