Hi - Strange problem. After deploying an application to a WebSphere 5.1 server using Network Deployment I get the error "ADMD0015W: Unable to join the multicast group: /" when starting the server. The message includes an IP address I don't recognize but which is defined as the "Node Multicast Discovery Address" in the nodeagent definition. In the node definition in Deployment Manager I have discovery protocol set to TCP not multicasting. This server had worked fine before deploying this latest app and I have several other servers on the same network that are still working properly. Any suggestions what I might be missing? Thanks!
