How to Fix 0x0 Remote Computer Requires Network Level Authentication (NLA)?
This error occures when you have some sort of group policy enabled by the domain controller and you are no longer part of it.
So, first, connect to your remote computer through IPMI or VNC and update the group policy.
gpupdate /force
Then, search and open "View Advanced System Settings".
Navigate to Remote and uncheck "Allow connections only from computers running Remote with Network Level Authentication (Recommended)".
Apply the changes and click on OK. Now, you should be able to login without any issues.
