MSMQ supports an MQPing command, not unlike the ping feature supported by the TCP/IP protocol. Use MQPing (for MSMQ Explorer) to determine if an MSMQ computer is currently connected to the network. When a computer running MSMQ receives an MQPing request, it returns the contents of the request to a private queue called mqping response.
When you ping a computer, MSMQ attempts to connect to the computer for 30 seconds and updates the computer icon accordingly. MSMQ Explorer displays one of the following symbols next to the computer's icon.

When you update the MSMQ Explorer display by pressing F5, MQPing status symbols are no longer displayed. However, pinging additional computers does not affect the ping status symbols already displayed.
To ping more than one computer, select multiple computers in the right pane of MSMQ Explorer before right-clicking a computer and clicking MQPing. To select a contiguous block of computers, hold down SHIFT and click the computers. To select non-contiguous computers, hold down CTRL and click the computers.
Note Pinging many computers generates significant network traffic in large enterprises. Ping all computers only when necessary, preferably when the network load is low.
