Block NetBIOS-based discovery for domain controller location

This policy setting allows you to control whether domain controller (DC) location algorithm uses NetBIOS_based discovery for domain controller location. If you enable or do not configure this policy setting, the DC location algorithm will never use NetBIOS-based discovery. This is the default behavior. If you disable this policy setting, the DC location algorithm may use NetBIOS-based discovery when necessary. The final behavior is further governed by the AvoidFallbackNetbiosDiscovery setting. NetBIOS-based discovery is considered unsecure, has many limitations, and will be deprecated in a future release. For these reasons, NetBIOS-based discovery is not recommended. See https://aka.ms/dclocatornetbiosdeprecation for more information.

This policy has no additional user input fields.
