You have a Windows Vista Service Pack 1 (SP1)-based or Windows Server 2008-based computer that is a member of a domain. When you disconnect from the network, you may experience a delay of 12 to 14 seconds before you can access the network again.
Notes- This issue usually occurs when the computer switches between a network that deploys Network Access Protection (NAP) enforcement and another network.
- This issue does not occur on a computer that is running the release version of Windows Vista or on a computer that is not a domain member.
This issue occurs because the Dynamic Host Configuration Protocol (DHCP) client sends ARP packets from Windows Networking Services.
When a client disconnects and then reconnects to a network, the client sends a new DHCP REQUEST packet. If the DHCP client belongs to a new subnet, the server responds to the client by using a DHCP negative acknowledgement (NAK) packet. Therefore, the client sends an address resolution protocol (ARP) request for the previously configured default gateway. However, no reply is received. Finally, after waiting 12 to 14 seconds, the client sends a DHCP DISCOVER packet. This packet starts a full renewal of the address.
