Hi there, When I use the message tracking tool or cmdlet the ServerHostname (eventidSEND) and clienthostname (eventid RECEIVE) are not populated on a messagetracking entry. Somehow the hostnames are not resolved'. DNS and even WINS is configured properly. Any settings that need to be altered to get the exchange server to resolve the hostnames when receiving or sending out messages?
