    Run the following commands on each impacted domain controller in order to regenerate all DNS entries required for domain controllers replication and authentication:

    # For A DNS record automatically:
    IPCONFIG /registerDNS 
        # For SRV DNS records
        Net stop netlogon 
        net start netlogon
