You have a single Active Directory directory service domain. A domain controller named DC1 cannot replicate with other domain controllers. DC1 holds no FSMO roles. You notice that the time on DC1 is 11:30 AM while the time on all the other domain controllers is 11:00 AM. You need to ensure that DC1 can immediately replicate with other domain controllers. What should you do?

A.
Modify the time on DC1 to match the time on the PDC emulator.

B.
Restart the Windows Time Service on the PDC emulator.

C.
Update the Windows firewall settings on the PDC emulator to allow outbound TCP/NTP traffic.

D.
