Method and system for restricting DHCP servers

A system for obtaining configuration parameters for connecting to a network, the system comprising:

• means for storing, under a control of a remote management computer that is connected to a client computer, a list of trusted configuration servers in a Remote Supervisor Adapter (RSA) card on the client computer;
• means for broadcasting a request for a configuration parameter from the computer to a plurality of configuration servers;
• means for receiving a response to the request for the configuration parameter at the client computer, the response being from a responding configuration server from the plurality of configuration servers;
• means for comparing an identity of the responding configuration server with the list of trusted configuration servers;
• means for upon verifying that the responding configuration server is on the list of trusted configuration servers, requesting configuration parameters from the responding configuration server;
• means for in response to determining that the responding configuration server is not on a list of trusted configuration servers, selecting, by the client computer, a selected server from one of the servers on the list of trusted configuration servers;
• and
• means for requesting, by the client computer, the configuration parameters from the selected server.

A computer program product, residing on a computer usable medium, for obtaining configuration parameters for connecting to a network, the computer program product comprising:

• program code for storing, under a control of a remote management computer that is connected to a client computer, a list of trusted configuration servers in a Remote Supervisor Adapter (RSA) card on the client computer;
• program code for broadcasting a request for a configuration parameter from the computer to a plurality of configuration servers;
• program code for receiving a response to the request for the configuration parameter at the client computer, the response being from a responding configuration server from the plurality of configuration servers;
• program code for comparing an identity of the responding configuration server with the list of trusted configuration servers;
• program code for, upon verifying that the responding configuration server is on the list of trusted configuration servers, requesting configuration parameters from the responding configuration server;
• program code for in response to determining that the responding configuration server is not on a list of trusted configuration servers, selecting, by the client computer, a selected server from one of the servers on the list of trusted configuration servers;
• and
• program code for requesting, by the client computer, the configuration parameters from the selected server.
