The DNS server could not configure the network connections of this computer with the local computer''s IP address as the preferred DNS server, because this computer is connected to networks with different or invalid DNS namespaces. Manual configuration of the local DNS server to perform name resolution on one or more of the namespaces is required before the preferred DNS servers of this computer should be modified.
If the network connections of this computer are not configured with the local computer''s IP address as the preferred DNS server, this computer may not be able to dynamically register DC locator records in DNS. Absence of these records may prevent other Active Directory domain controllers and domain members from locating this domain controller.
Ensure that DC locator DNS records enumerated in the file %SystemRoot%\system32\config\netlogon.dns are registered on the local DNS server. If these records are not registered in DNS:
a) Add a delegation to this DNS server to parent DNS zone matching the name of the Active Directory domain OR
b) Configure the local DNS server with appropriate root hints and forwarders (if necessary) and configure the network connections of this computer with the local computer''s IP address as the preferred DNS server. Note that other computers using other DNS servers as their preferred or alternate DNS servers may not be able to locate this domain controller, unless the DNS infrastructure is properly configured.
