SYMPTOMS

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.

MORE INFORMATION

The GUID of a network adapter may change when you upgrade a computer to Windows Vista. The GUID may also change if the network adapter's configuration changes from Dynamic Host Configuration Protocol (DHCP) to static IP and then from static IP to DHCP. The old GUID and its associated IP addresses are not cleared from the DNS client configuration. Therefore, the old IP addresses remain registered for the computer. In this situation, the authoritative zone on a DNS server is populated with both IP addresses that are not valid and IP addresses that are valid. A DNS server cannot distinguish between IP addresses that are valid and IP addresses that are not valid. Therefore, when a DNS server responds to queries from client computers, the server may distribute an IP address that is not valid. If another client computer tries to use this IP address, the computer experiences a connection failure.
