RDPCheck is the local RDP test utility bundled with RDP Wrapper. Its v1.6.2 source connects to the host's configured RDP listener through 127.0.0.2; it is not a general remote-desktop client or remote-execution tool. Before connecting, the source attempts to set the local RDP-Tcp SecurityLayer and UserAuthentication registry values to 0, then attempts to restore the saved values in its disconnection handler. Use only on an authorized test host and verify the settings after exit.
