Publisher messages not reaching subscriber - nservicebus

Publisher config

When i run pub and sub from diffrent machines, the messages from publisher don't reach subscriber. If I run them on the same machine they work fine.
=> the publisher is running on this machine and publisher queue is created locally.
is same as
=> the machine on which subscriber is running.
The profile is production and there is no exception in the log file.
Any clues why messages are getting dropped.
Thsnks for the help...

Answer 1

Check the internal outbound queue on the Publisher. If you see messages there this means it can't communicate with the Subscriber. This usually means that you may not have MSDTC running or the security for MSDTC is not correctly configured. Make sure you have "Allow Inbound" and "Allow Outbound" set in the MSDTC security settings.

I wanted to chuck my mouse at someone when I got mine working.
For me, the problem was that I was trying to send a plain poco class as my message.
app.config
<UnicastBusConfig ForwardReceivedMessagesTo="audit">
<MessageEndpointMappings>
<add Assembly="Messages" Endpoint="pub" />
</MessageEndpointMappings>
</UnicastBusConfig>
Then I thought maybe I need to tell what the object is supposed to be, so I configured the message as a message
Configure.With()
.DefiningMessagesAs(t => t.Namespace != null && t.Namespace.Contains("Messages"));
Still didn't work, so then for grins i changed it to this
Configure.With()
.DefiningEventsAs(t => t.Namespace != null && t.Namespace.Contains("Messages"));
Now it works fine
