Abstract

A system and method for remotely connecting client computers to a communication network such as the Internet by way of a server system and dynamically providing network connections to the client computers, including changing static communications settings to dynamic settings.

Claims

1. A communications apparatus for providing communication between a client system and an electronic communications network (ECN), the client system having a plurality of communications settings and the client system running client software for managing the communications between the client system and the ECN, the apparatus comprising:

a determiner for determining if communications settings are properly set in the client system for communication between the client system and the ECN;

a memory for storing at least a first communications setting in the client system when the communications settings are not properly set;

a requestor for requesting at least the first communications setting from an external server system via an access port and for receiving a new value of at least the first communications setting from the external server system via the access port;

a changer for changing at least the first communications setting in the client system when the communications settings are not properly set.

2. An apparatus according to claim 1, further comprising;

a rebooter for rebooting the client system when the communications settings are not properly set.

3. An apparatus according to claim 2, wherein said memory may store an IP address and a DNS address.

4. An apparatus according to claim 2 wherein the first communications setting saved in said memory includes an IP address.

5. An apparatus according to 1, wherein said access port to which the client system is connected is a hot access port.

6. An apparatus according to claim 1, further comprising;

a conductor for conducting an ECN session wherein the first communications setting is used in the ECN session.

7. An apparatus according to claim 6, wherein the ECN session is an Internet session.

8. An apparatus according to claim 1, wherein said memory may store at least the first communications setting in a non-volatile manner.

9. An apparatus according to claim 1, wherein said determiner also determines if settings selected from the group consisting of:

network configuration settings and control settings are properly set.

10. An apparatus according to claim 1, wherein said determining also determines if settings selected from the group consisting of:

IP address, gateway address, DNS address, network logon preferences, file sharing settings, and browsing control settings are properly set.

11. A communications apparatus for providing communication between a client system and an electronic communications network (ECN), the client system having a plurality of communications settings and the client system running client software for managing the communications between the client system and the ECN, the apparatus comprising:

a determiner for determining if the client system is configured to receive a new value for a first communication setting;

a memory for storing a first value of at least the first communications setting when the client system is configured to receive the new value for the first communications setting; and

a requester for requesting at least the first communications setting from an external server system via an access port, for receiving a new value of at least the first communications setting from the external server system via the access port, and for setting at least the first communications setting using the first communications setting.

12. An apparatus according to claim 11, wherein the first communications setting is selected from the group consisting of:

an IP address and a DNS address.

13. An apparatus according to claim 11, further comprising:

a configurer for configuring the client system to receive the new value for the first communications setting.

14. An apparatus according to claim 11, further comprising:

an inquirer for inquiring whether a user of the client system desires to change a communications settings configuration of the client system.

15. An apparatus according to claim 11, wherein the client system has a predetermined value for at least the first communications setting and the apparatus further comprises:

a disabler for disabling the predetermined value of at least the first communications setting.

16. An apparatus according to claim 11, further comprising:

a rebooter for rebooting the client system.

17. An apparatus according to claim 11, further comprising:

an initializer for initalizing the client system with the new value of the first communications setting.

18. An apparatus according to claim 17, further comprising:

a restorer for restoring the first value of the first communications setting.

19. An apparatus according to claim 18, wherein said restorer further comprises:

a saver for saving the new value of the first communications setting in said memory.

20. An apparatus according to claim 11, further comprising:

a rebooter for rebooting the client system;

an initializer for initializing the client system with the new value of the first communications setting;

a restorer for restoring the first value of the first communications setting; and

a saver for saving the new value of the first communications setting in said memory.

21. An apparatus according to claim 11, wherein said access port to which the client system is connected is a hot access port.

22. An apparatus according to claim 11, wherein the first communications setting is initially a static setting and the apparatus further comprises:

a configurer for configuring the client system to receive the first value, said configurer including a changer for changing the first communication setting to dynamic from static when said determiner determines that the client system is not configured to receive the new value.
