Keeping track of workstation IP address history
My network has two Win 2003 servers each running a DHCP service. This means that when a lease expires it can be a race to to find the first available address from either server so machines frequently change IP address.
I need to be able to keep track of the IP address history of each workstation on my network (300+ XP machines) for at least the previous 2 weeks. I know I can look up their present IP address in the DNS but I want a simple quick way to be able to check the IP a machine was using at any given time over the past fortnight.
