RDP: credSSP error

아래 내용을 참고해서 레지스트리 값을 추가

"The quick fix as it turns out is to add a single key to your workstation's registry.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\CredSSP\Parameters] "AllowEncryptionOracle"=dword:00000002

In my case I had to create the CredSSP key, then the Parameters key, then the dword value as none of them existed.

No need to reboot, I could then immediately connect to remote desktop."
