1. A method for reconfiguring a network, the method comprising:

  • setting by a client a renew time and a rebind time of a dynamic host configuration protocol (DHCP) configuration;

    establishing by the client an IP address with a first DHCP server, the IP address having a specified lease time;

    after passage of the renew time, transmitting by the client a renew request to the first DHCP server at its IP address;

    in response to failure to receive an acknowledgement message from the first DHCP server, determining by the client if the first DHCP server IP address is still valid;

    in response to determining that the first DHCP server IP address is not still valid, retrieving by the client a second, different DHCP server IP address from a network change event signal; and

    configuring by the client a network adapter based on the second DHCP server IP address.
