Always give specified static internal IP to a certain client computer

[startup]

We are running Windows Server 2003 VPN giving out IPs from a static address pool. Is there any way, either with the static address pool, or with DHCP to give a specified client computer the same internal address (ie 10.100.1.1) every single time it connects? Currently the client gets a different IP every time he connects. He has a custom application which requires him to have the same internal address all the time. Is there any way to do this with Microsoft VPN setup or with any other VPN systems?
Thanks
