Emma realizes that the custom application submits revers lookup requests to the DNS server to discover the host n for the specified IP address. During a random test, she finds that the program is not reporting the host names for some clients, even though it properly records their IP addresses. Emma has been asked to test the new application. As part of a new security initiative, the IT department has developed a custom application that reports the host name of each client that tries to access three sensitive servers in the Accounting department.
All hosts are members of the domain, the records of which are stored in a primary zone. All servers are running Windows Server 2012 and all clients are running Windows 8. The network has multiple domains with DNS and DHCP services confgured in each domain. Emma is a systems administrator for WestSim Corporation.
