I have a number of computers with different hostnames connected to the network. They currently hold a static IP address based on their MAC address. In other words, the static IP address is mapped to their MAC address. This gives rise to a problem and that's when we swap the harddrive from one computer to another, the MAC address becomes different and the application we are running on the harddrive has problem getting the right static IP for it to work.

We can't configure the IP address in the application all the time. And changing the static IP addresses to re-map to the computer's new MAC address can be quite a pain.

Since all the computers have a unique computer name as their hostname, is it possible to configure such that when these computers grab IP addresses from the DHCP server, DHCP will learn about their hostname and assign the correct IP address? This is to say, the static IP is mapped to the computers' hostname instead of their MAC address.

All the computers are running on Windows 7.

Would this be possible? If so how should I go about do this?
