A corporate environment includes 10,000 client computers running Windows 7 Enterprise. The client computers are joined to an Active Directory Domain Services (AD DS) domain named contoso.com. DNS is the preferred name-resolution protocol. There have been no recent changes to the DNS entries. WINS is not running in the environment. When most users attempt to connect to pc01.contoso.com from their client computers, the URL resolves to the incorrect IP address. The URL resolves correctly from only one client computer. On the client computers experiencing the issue, the HOSTS file does not include an entry for pc01.contoso.com. You need to recommend an approach for resolving pc01.contoso.com correctly from all client computers. What is the best approach to achieve the goal? (More than one answer choice may achieve the goal. Select the BEST answer.)
A.
Run the ipconfig /flushdns command from the client computers experiencing the issue.
B.
Add a pc01 entry pointing to the correct IP address to the LMHOSTS file on each of the client computers experiencing the issue.
C.
Add a pc01.contoso.com entry pointing to the correct IP address to the HOSTS file on each of the client computers experiencing the issue.
D.
Run the ipconfig /registerdns command from PC01.
