Issue

Getting the error ‘An Authentication Error Has Occurred .The encryption type requested is not supported by the KDC’ when RDP to windows servers

Resolution

Restart the KDC ( ( KERBEROS DISTRIBUTION KEY ) ) services on your domain controllers. The issue occurred after raising the functional level from windows 2003 to Windows R2. Then its resolved after restarting the KDC services on domain controllers.
