'            Exchange server, and the Unreachable
'            property on the ExchangeServerState instances.
' Input:     strComputerName [string] the computer to access
' Output:    Displays the name of each ExchangeServerState and
'            Unreachable property
'===============================================================
Public Sub ShowServerState_Unreachable ( strComputerName )

Const cWMINameSpace = "root/cimv2/applications/exchange"
Const cWMIInstance = "ExchangeServerState"

Dim strWinMgmts              ' Connection string for WMI
Dim objWMIExchange           ' Exchange Namespace WMI object
Dim listServerStates         ' ExchangeServerState collection
Dim objExchangeServerState   ' A single ExchangeServerState object

' Create the object string, indicating WMI (winmgmts), using the
' current user credentials (impersonationLevel=impersonate),
' on the computer passed to the function in strComputerName, and
' using the CIM namespace for the ExchangeServerState provider.
strWinMgmts = "winmgmts:{impersonationLevel=impersonate}!//" & _
   strComputerName & "/" & cWMINameSpace
'
' Get an object using the string you just created.
Set objWMIExchange =  GetObject(strWinMgmts)
'
' The current state of each Exchange server is
' represented by an ExchangeServerState instance
' within the Exchange namespace.
Set listServerStates = objWMIExchange.InstancesOf(cWMIInstance)
'
' Were any ExchangeServerState instances returned?
if (listServerStates.count > 0) then
  ' If yes, do the following:
  ' Iterate through the list of ExchangeServerState objects.
  For each objExchangeServerState in listServerStates
     '
     ' Display the value of the Name property.
     WScript.echo "Name = [" & _
       TypeName(objExchangeServerState.Name) & "] " & _
      objExchangeServerState.Name
     '
     ' Display the value of the Unreachable property.
     WScript.echo "    Unreachable = " & _
      "[" & TypeName(objExchangeServerState.Unreachable) & "] " & _
       objExchangeServerState.Unreachable
     '
     '
     ' Move to the next ExchangeServerState.
  Next
else
  ' If no ExchangeServerState instances were returned,
  ' display that.
  WScript.Echo "No ExchangeServerState instances were returned."
