What you see in the Progress explorer is the admin server of the host connected. The settings are not stored in the Progress explorer, they are stored in the configuration file of the admin server. Usually you'll find this file on the server in the properties folder beneath the Progress installation folder and it's name is ubroker.properties.
You will see this settings from any client that has the Progress explorer installed - the only restriction is, AFAIK, the Progress/OpenEdge version installed on the server and on the client must exactly match, down to the patch level.
HTH, RealHeavyDude.
