Locate Summary Error: ENDS14
Either More than one DNSDHCP/dhcpLocator or none of the DNSDHCP and dhcpLocator objects was found. The DNS/DHCP NDS schema may not be installed properly.

The tree have DSfW service running, and the related DNS/DHCP object in other OU had been deleted, but still get the same error.

Any idea? how to check my tree schema is ok?
