Description:
IcMon (InConcert Server Monitor) will not work correctly with non-default Rendezvous.  IcMon looks in the Windows registry for HKEY_LOCAL_MACHINE\SOFTWARE\TIBCO Software Inc.\InConcert Server Monitor\6.2.1 which is only present if you have upgrade TIBCO InConcert for that version.  It looks for that entry regardless if the version of the software is 7.1, 7.2.x or 7.3.

You can either copy the existing 7.1 or 7.2 registry entries and update all 7.x.x entries in the copied key to 6.2.1; or you can import the TIBCO Resolution Document for the registry entries.  This is from a Windows XP host.

Once the changes have been made in the Windows registry start IcMon; open Tools/Options and set the appropriate TIBCO Rendezvous settings.  The settings will not take affect UNTIL you stop and restart IcMon.
