I am having this same issue… any suggestions please? Thank you!
I am installing Vantage 8.03.408B (SQL db) on a new virtual server (my current server is dying a slow and painful death) and get an error message every time I try to start the AppServers in Progress Explorer. It starts but stops before it can become active with a message of “This broker is no longer active (CMNMsg028)”. Most likely it’s just a setting or step I overlooked.
Can anyone offer any suggestions?
