You have a single Active Directory directory service domain with Windows XP client computers. Some users receive their DNS suffix search orders by using DHCP, and some users configure their DNS suffix search orders manually. You link a new Group Policy object (GPO) to the domain to specify a DNS suffix search order for client computers. Some users report that they are not receiving the new DNS suffix search order from the GPO. You need to ensure that all users receive the DNS suffix search order from the GPO. What should you do?

A.
Remove the DNS suffix search order from the DHCP server scope.

B.
Remove the manually entered DNS suffix search order on the client computers.

C.
Modify the GPO to enable dynamic DNS registration.

D.
Enforce the link on the GPO.
