3. Verify the attribute "msDS-DnsRootAlias". If any value does exists,
clear the value. i.e. msDS-DnsRootAlias: <not set>
4. Force replication to all the domain controllers.
5. Rename the netlogon.dns and netlogon.dnb file in
%systemroot%\system32\config directory on the problematic domain controller.
