Using MSMQ Explorer, you can send test messages from any MSMQ independent client or server to a test queue on any other independent client or server within the same enterprise. You can use MSMQ Explorer to create test queues or change the type ID of existing queues so that you can send test messages to the queues.
Note Test queues have a type ID of {55EE8F33-CCE9-11CF-B108-0020AFD61CE9}. If you change the type ID of a transactional queue to {55EE8F33-CCE9-11CF-B108-0020AFD61CE9} and send test messages to the transactional queue, the messages are not delivered. Only transactional messages can be sent to transactional queues, and MSMQ Explorer test messages are not transactional. Similarly, if you change the type ID of a queue requiring authentication to {55EE8F33-CCE9-11CF-B108-0020AFD61CE9} and send test messages to the queue, the messages are not delivered (unless the target queue is located on the sending computer).
