Technically a router is nothing more than just another specialized computer, and if the router is handing out the dynamic IPs, or even static IPs based on MAC addresses, then it could be involved in the problem. Your man, or someone helping him, probably created a new configuration on the computer, which defaults to a dynamic address.
Are we talking about a local LAN with LAN/WAN router acting as a gateway, a local network connected to a router acting as a router connecting two or more networks together, or a public network. Some router can probe the up-link of the network to obtain thier static WAN IP address, usually assigned dynamically, and some networks require the connecting router/computer to be issued a dynamic IP. ISP like dynamically assigned IPs, so they can recycle IPs as leases expire without the need to add additional hardware. Even in large, publically traded companies most computers have a local IP that is connected to a switch, hub, or router/gateway; otherwise, we would run out of Public IPs.
