Dear Maintainer, rdesktop fails to commect to windows 10 pro host running on local network: $rdesktop 192.168.122.86 ERROR: CredSSP: Initialize failed, do you have correct kerberos tgt initialized ? Failed to connect, CredSSP required by server Firewall on the Win 10 machine is completely down, and remote settings are set to be as permissive as possible. xfreerdp /v:192.168.122.86 works without a hitch.
