Enumerating Remote Nodes

  • Article

This example demonstrates enumerating remote nodes on a Network Load Balancing (NLB) cluster.

strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\MicrosoftNLB")
Wscript.Echo ""
Wscript.Echo ""
Wscript.Echo "MicrosoftNLB_Node"
Wscript.Echo "================="
Wscript.Echo ""
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\MicrosoftNLB")
Set colItems = objWMIService.ExecQuery("Select * from MicrosoftNLB_Node",,48)
For Each objItem in colItems
  Wscript.Echo "ComputerName:       " & objItem.ComputerName
  Wscript.Echo "CreationClassName:  " & objItem.CreationClassName
  Wscript.Echo "DedicatedIPAddress: " & objItem.DedicatedIPAddress
  Wscript.Echo "HostPriority:       " & objItem.HostPriority
  Wscript.Echo "Name:               " & objItem.Name
  Wscript.Echo "StatusCode:         " & objItem.StatusCode  & _
               " (only correct for connected host - " & strComputer & ")"
  Wscript.Echo ""

  Wscript.Echo "Connecting to this node directly (to get the correct host state)..."
  Set objWMIService2 = GetObject("winmgmts:\\" & objItem.ComputerName & _
                                 "\root\MicrosoftNLB")
  Wscript.Echo "Connected to this node (via " & "winmgmts:\\" & _
                objItem.ComputerName & "\root\MicrosoftNLB" & ") ..."
  Set colItems2 = objWMIService2.ExecQuery("Select * from MicrosoftNLB_Node",,48)
  For Each objItem2 in colItems2
    If objItem.ComputerName = objItem2.ComputerName Then
      Wscript.Echo "Correct StatusCode: "      & objItem2.StatusCode
    End If
