You are a systems administrator for WestSim Corporation. As part of a new security initiative, the IT department has developed a custom application that reports the host name of all clients that try to access three sensitive servers in the accounting department. The application has been working for the last three months. The company expands and adds a new building with a LAN connection to the rest of the network. This building has its own subnet, 192.168.5.0. You create a scope on an existing DHCP server for this subnet.

During a random check of the reporting software, you discover that the application reports the IP address but not the host name for clients on the new subnet. Everything works as designed for hosts on other subnets. You check the DNS database and find that none of the hosts on that subnet have an associated PTR record.

What should you do?
