[1/3/05 14:37:23:794 EST] 68a26113 MulticastServ W ADMD0015W: Unable to join the multicast group: <hostname>/<IPaddress>
 
Cause
Incorrect entry in the serverindex.xml file. For example,
<specialEndpoints xmi:id="NamedEndPoint_1093456671804" endPointName="NODE_MULTICAST_DISCOVERY_ADDRESS">
<endPoint xmi:id="EndPoint_1093456671806" host="<hostname>" port="7842"/>
 
Answer
Replace host name with IPaddress of group it needs to join for only NODE_MULTICAST_DISCOVERY_ADDRESS.
Other endpoints need not be changed. For example,
<specialEndpoints xmi:id="NamedEndPoint_1104917713551" endPointName="NODE_MULTICAST_DISCOVERY_ADDRESS">
<endPoint xmi:id="EndPoint_1104917713552" host="IPaddress" port="7842"/>
