A client computer that is running Windows Vista registers an old IP address when the GUID of a network adapter changes
When the GUID of a network adapter changes on a client computer that is running Windows Vista, the computer registers an old IP address that was associated with the old GUID.
The client computer also registers new IP addresses that are associated with the new GUID. However, because the client computer registers old IP addresses, another client computer may try to use the old IP address. If the old address is not valid, a connection failure may occur.
