Hello, error code 0xc07 typically indicates a connection or authentication-related problem when trying to establish a remote desktop session with a Windows-based computer or server. It looks like you've tried a few things, including running secpol.msc to open the Local Security Policy. You can directly open the Type 'local security policy Search in Windows Search, select Local Policies > Security Options, and disable Console login only for local accounts with blank passwords.
In addition, check the Remote Desktop Service running again: Open Control Panel -> Administrative Tools -> Services, find Remote Desktop Service and Remote Desktop Configuration, and change the startup type to automatic.
