DNS Soru 10:

You administer a Windows Server 2003 Active Directory domain with 100 Windows NT 4 Workstation clients. The clients are statically configured, and they have static entries in the DNS zone domain1.local. DNS is Active Directory–integrated and allows only secure dynamic updates. You upgrade all your clients to Windows XP Professional.You install DHCP, and you configure your clients to obtain their IP configurations and their preferred DNS server addresses automatically. DHCP is configured to always update client records in DNS. Clients report that they can no longer access other clients by host name. You examine the DNS database and find that A resource records are not being updated, but PTR resource records are. How should you solve this problem?

A. Reconcile the DHCP scope.

B. Manually delete all the static A resource records. Run Ipconfig /registerdns on

each client computer.

C. Run Dnscmd /ageallrecords domain1.local.

D. Run Dnscmd /startscavenging.
