We have one distributor/publisher (NSB community version, which is on a domain but recently changed to workgroup mode due to some issues), which communicates to two workers on two different servers (on domain). All of a sudden it is not sending any work to one of the workers where as the worker has sent several acknowledgements which were unacknowledged by the publisher.
Please help - whether this is a bug in NSB host or am i missing something here?
Finally found the issue, it is not related to Nservicebus, rather it is related to network. The servers were unable to communicate each other due to some security/firewall problems.
Solution is: Adding the host entries of subscribers (worker servers) in the publisher (distributor) has solved the same.
