Microsoft Message Queue (MSMQ):
MSMQ is a messaging protocol that allows applications running on separate servers/processes to communicate in a failsafe manner. A queue is a temporary storage location from which messages can be sent and received reliably, as and when conditions permit. Queues are used to receive and send the Messages.
To Install MSMQ, Go to Control Panel -> Add Remove Program -> Add Windows Component and select “Message Queuing”
