Windows DHCP Networking – CHCPCORE.DLL
Dhcpcore.dll and dhcpcsvc.dll are provided by Microsoft as part of your Windows operating system. These files manage network configuration by registering and updating IP addresses and DNS names. You'll need these files if you run a DHCP-based network. They are also required by some Cable or DSL service providers. In this case, they generate a dynamic IP address so that you can connect to the Internet. The default setting for the dhcp service is 'automatic'. We'd recommend leaving it in place.
