WMI Mapper
If you have created subscriptions on a Windows managed system and then elect to change the WMI Mapper
proxy or install a WMI Mapper on the managed system, you must first unsubscribe for WBEM events, change
the proxy, re-identify the systems, and then resubscribe for WBEM events. If you do not unsubscribe for the
WBEM events, Systems Insight Manager will no longer receive indications from the managed system.
