I used the example "Completing a Conversation Between Instances" from SQL Server 2008 Books Online, but when I try to send a message, it does not go through, and in sys.transmission_queue.transmission_status I see the above error.
I tried this between two different computers, and also between a desktop and a VPC running on it, I tried various ports, but nothing helps.
On the profiler I see no activity on the target side.
Thanks for any help.
