If you're assigning a static IP address to a network card via windows TCP/IP settings - is there anything that could make it revert back to ... I dunno... either getting a DHCP assigned address, or some other (old) static IP address?
Could it be an identical IP Address already exists on the network?
I can't think of anything (else).
