MSMQ - Time To Be Received Timing Out

I am sending the same transactional message via C# to 3 transactional MSMQ queues I have set the time to be received from 5second up to 900seconds.

Dead letter logging is on

All the permissions on all 3 queues are identical The target queues are: 2 private queues on the sending machine 1 public queue on a 开发者_如何学编程remote machine

No matter how many times I repeat this, 2 of the sends fail. I have verified when sending the message into MSMQ the time to be received is 5s.

1 private queue on sending machine works the other 2 wind up in the dead letter queue

How can I troubleshoot this? It's always the same queue that works and the same queue that fails no matter which order they are sent in.

Never mind, the services reading from the other queues weren't running. Apparently to be properly 'received' something has to do the receiving!
