Autonomic removal of a user from a client and network

A method comprising:

• providing at a lease server a lease renewal parameter for each client on a network;
• and
• responsive to a receipt of a lease renewal request generated during an attempt by a user to log on to a client, transmitting a value of the lease renewal parameter to the client, wherein:
• when said value indicates a non-renewal of said lease, said client is triggered to prevent said user from accessing either said client or said network.

A computer program product comprising:

• a computer readable medium;
• and
• program code on said computer readable medium for completing a method comprising:
• issuing to a network server a lease renewal request when a user attempt to log on to a client is registered;
• when a lease renewal response indicates that a renewal of a lease by a lease server, enabling the user to log on and access the client and network;
• and
• when the lease renewal response indicates a non-renewal of the lease, preventing the user from accessing either the client or the network.

A network comprising:

• a lease server that completes the method of:
• providing a lease renewal parameter for each client on the network;
• responsive to a receipt of a lease renewal request generated during an attempt by a user to log on to a client,
• transmitting a value of the lease renewal parameter to the client, wherein said packet is transmitted to said client via one of a directed transmission or a broadcast;
• and
• when said packet is issued via a broadcast, continuing said broadcast until a reply packet is received from the client;
• wherein:
• when said value indicates a non-renewal of said lease, said client is triggered to prevent said user from accessing either said client or said network;
• and
• when said value indicates a renewal of said lease, triggering said client to allow said user to access said client and said network;
• and
• a client that completes the method of:
• issuing to the network server a lease renewal request when a user attempt to log on to a client is registered;
• receiving the lease renewal response within a packet transmitted from the lease server;
• generating a reply packet indicating receipt of the lease renewal response;
• transmitting the reply packet to the lease server;
• when a lease renewal response indicates that a renewal of a lease by a lease server:
• verifying that said user has entered a correct user credential for accessing the client and network;
• enabling the user to log on and access the client and network;
• and
• providing said user with access to a hard drive and data on said client and said network;
• when the lease renewal response indicates a non-renewal of the lease, preventing the user from accessing either the client or the network:
• resetting a user access credential to an administrative credential, whereby the administrative credential is required to access said network from said client;
• triggering a basic input/output system (BIOS) of the client to return the client to an initial login phase, wherein said triggering includes initiating a restart of said client.
