    Does anyone know if it possible to instantiate objects remotely using vbs or
    powershell? Right now I am trying to use psexec to execute a batch file that
    calls a local script on a server to deploy patches using the WSUS client.
    The problem is that when I try to use this object Set objDownloader =
    objSession.CreateUpdateDownloader() and some of the others I get access
    denied. But if remote desktop onto the server it works without any
    permission problems. With psexec I have tried the -u parameter so it should
    not be using impersonation but the domain admin creds. I have a hole in my
    knowledge on using objects like this remotely so any help or experiences
    would be helpful. Thanks.

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set objAutomaticUpdates = CreateObject("Microsoft.Update.AutoUpdate")
    Set objComputer = CreateObject("Shell.LocalMachine")

    Wscript.Echo "Server name: " & objComputer.MachineName

    ' Search for updates

    Set objSession = CreateObject("Microsoft.Update.Session")
    Set objSearcher = objSession.CreateUpdateSearcher()
    Set objResults = objSearcher.Search("IsInstalled=0 and Type='Software'")
    'Set objResults = objSearcher.Search("Type='Software'")
    Set colUpdates = objResults.Updates

    ' List out updates that were found.
    For each objUpdates in colUpdates
    Wscript.echo objUpdates
    objPatchRecordset("Name") = objComputer.MachineName
    objPatchRecordset("Patches") = objUpdates


    ' Download Updates if needed
    Set objUpdatesToDownload = CreateObject("Microsoft.Update.UpdateColl")
    intUpdateCount = 0
    For i = 0 to colUpdates.Count - 1
    intUpdateCount = intUpdateCount + 1
    Set objUpdate = colUpdates.Item(i)

    If intUpdateCount = 0 Then
    WScript.Echo "No Patches to Install!"
    Set objDownloader = objSession.CreateUpdateDownloader()
    objDownloader.Updates = objUpdatesToDownload

    ' Install updates
    Set objInstaller = objSession.CreateUpdateInstaller()
    objInstaller.Updates = objUpdatesToDownload
    Set installationResult = objInstaller.Install()

    ' Reboot server if needed
    Set objSysInfo = CreateObject("Microsoft.Update.SystemInfo")
    If objSysInfo.RebootRequired Then
    Set objWMIService =
    Set colOperatingSystems = objWMIService.ExecQuery _
    ("Select * from Win32_OperatingSystem")
    For Each objOperatingSystem in colOperatingSystems
    End If
    End If
