Symptoms

Consider the following scenario:
  • You install Internet Information Services (IIS) 7.5 on a computer that is running one of the following operating systems:
    • Windows Vista
    • Windows Server 2008
    • Windows 7
    • Windows Server 2008 R2
  • You run a Windows script to connect to the Windows Management Instrumentation (WMI) WebAdministration namespace.
    For example, you run the following VBScript script:
    Set oIIS = GetObject("winmgmts:root\WebAdministration")
    Set oSite = oIIS.Get("Site.Name='Default Web Site'")            
    WScript.Echo "Retrieved an instance of Site "         
    WScript.Echo "        Name: " & oSite.Name
    WScript.Echo "        ID:   " & oSite.ID
    Set objInParam = oSite.Methods_("GetState"). _
        inParameters.SpawnInstance_()
    For i = 0 to 10000
       Set objOutParams = oIIS.ExecMethod("Site.Name='Default Web Site'", "GetState", objInParam)
       Wscript.Echo "Out Parameters: "
       Wscript.Echo "ReturnValue: " & objOutParams.ReturnValue
       WScript.Echo "LoopCount : " & i
       objOutParams = NIL
       Wscript.Echo "NIL is " & objOutParams
       
    Next
    oSite.Stop
In this scenario, a memory leak may occur in the WmiPrvSe.exe process.
