Here is outstanding interview question by Sirak Mulatu, if servers need static IP address as best practices, why the DHCP client service needs to be running on the Exchange server. Best practice is to disable all unnecessary services to make exchange even stronger?
Fair enough the service DHCP Client is being used to register DNS names. "Manages network configuration by registering and updating IP addresses and DNS names.". Imagine registration won't happening active directory integrated DNS world. The clients who needs mail service, won't be able to locate the Exchange server due to missing records, which will drop the entire Exchange server off from a network,
This will create a disaster in the SMTP mail flow. Be careful about this service.
