'            objects
' Change:    cComputerName [string] the computer to access
' Output:    Displays the name of each Exchange_Logon and Latency property
'===============================================================

' Create the object string, indicating WMI (winmgmts), using the
' current user credentials (impersonationLevel=impersonate),
' on the computer specified in the constant cComputerName, and
' using the CIM namespace for the Exchange provider.
