Which of the following is the most likely cause of this problem?
A)DNS is not integrated with the Active Directory.

Question

Quizplus · Accepted Answer

The DHCP server's computer account is not a member of the DNSUpdateProxy global security group.
Key Takeaway: In this case, the clients cannot perform this task because the DHCP server owns the A records. You should add the DHCP server to the DNSUpdateProxy group. Members of this group can update resource records but do not own them. In addition to adding the server to DNSUpdateProxy group, you should manually delete the clients' host records and then either reboot the clients or use the Ipconfig /registerdns command-line utility on each client.
