Is there any way to force Windows to reboot itself remotely when rdesktop fails completely? I can't get it to accept any form of key combination or at a minimum, it is unresponsive to ctrl+shift+end/del/win+b/etc. I'm using a Microsoft account so psexec is a no go.
rdesktop accepts my credentials and begins logging on, but then ends with the standard "Your Remote Desktop Session has ended..."
It seems something breaks during the login itself. Microsoft's rdesktop client uses Network Level Authentication (NLA) and pre-auths your creds before connecting to the session, but Linux's rdesktop does not.
On a hunch that something was happening with NLA/during the login sequence, I connected via rdesktop on Linux and it dropped me to the login screen. Interestingly, attempting to login still failed however, I was able to simply reboot the host with the power button on the login screen.
TLDR: Try rdesktop from Linux and see if it gets you the login splash screen and then reboot.
