While writing the previous post I made a mistake in copying the excerpt of my configuration file. The actual one I am using is:
<Partitioning> <GlobalPartition Address="224.0.0.42"/> <NetworkPartitions> <NetworkPartition Address="N2 N3 N4 N5" Connected="true" Name="part"/> </NetworkPartitions> <PartitionMappings> <PartitionMapping DCPSPartitionTopic="part.*" NetworkPartition="part"/> </PartitionMappings> </Partitioning> Sorry for the double post, and thanks again for any help you will provide.
