A method and system for managing a secure configuration of a server blade on a network. The server blade has a Remote Supervisor Adapter (RSA) card, which contains a list of trusted Dynamic Host Configuration Protocol (DHCP) servers. A remote manager, which communicates with the RSA card via a hyper-secure network, maintains the list of trusted DHCP servers on the RSA card. When the server blade broadcasts a request for configuration parameters to join the network, a response offer is returned from a DHCP server. If the responding DHCP server is not on the list of trusted DHCP servers contained in the RSA card, then the offer is refused, and another DHCP server's offer is evaluated.

A method and system for managing a secure network boot of a server blade. The server blade is part of a server blade chassis, which holds multiple server blades that communicate with outside devices via a Pre-boot eXecution Environment (PXE) enabled network interface card. When a server blade receives a response from a PXE boot server offering a boot program download, a Remote Supervisory Adapter (RSA) card, managed by a remote manager, compares the identity of the responding PXE boot server with a list of trusted PXE boot servers. Only if the responding PXE boot server is on the list of trusted PXE boot servers will the server blade be allowed to use a boot program provided by the responding PXE boot server.

An integrated telecommunication collaboration system which allows the close integration of desktop computer applications, data communications, and public switched telephone network voice connections. Client software which implements the invention includes a voice agent for establishing telephone sessions, a data agent for establishing associated data sessions, a communications agent which synchronizes the date and voice agents, and an integration agent which integrates the data and voice communications with a computer operating system, and with various applications. The integrated telecommunication collaboration system controls the establishment of harmonized calls by sending and receiving various requests and status messages to and from a server, and another client.
