1. A method for ensuring a connection to a configuration protocol server on a data network by a customer premises equipment via a network connection, the method comprising the steps of:
- issuing a request for a customer premises equipment network address from the customer premises equipment to the configuration protocol server via the network connection;
the network connection determining whether a connection can be made to the configuration protocol server, and if not, responding to the customer premises equipment by sending a temporary network address and a lease time to the customer premises equipment, whereby the lease time limits the time of validity of the temporary network address;
issuing a request to renew the temporary network address when the lease time expires;
the network connection determining whether a connection can be made to the configuration protocol server, and if not, responding to the customer premises equipment by sending an acknowledge message;
when the network connection determines that the connection can be made to the configuration protocol, the network connection sending a NACK message declining to acknowledge the request to renew the temporary network address;
the customer premises equipment receiving the NACK message and sending a request for the customer premises equipment network address; and
the network connection communicating the request for the customer premises equipment network address to the configuration protocol server.

Abstract
A system and method for ensuring a connection to a configuration server by a customer premises equipment. The customer premises equipment is connected to a data network via a network connection. The data network includes a connection to the data network. A temporary configuration server is included to respond to configuration messages from the customer premises equipment before the network connection is capable of sending messages over the data network.
