Using Windows Server 2003 and XP Professional workstations, how do you force a workstation to acquire a new and different IP address from the one it already has? With DHCP, IP addresses already in use tend to renew on the same machine over and over again. If I want to assign a specific workstation a different address I'm releasing the existing IP, then deleting the lease on the server under DHCP, then manually entering a new address on the workstation and rebooting. That seems like too much work. Is there an easier way?
