Stale Computer Search Yields Computers That Do Not Exist In Active Directory

[Robdog1955]

I have a script to search Active Directory for stale computers within a given OU. The search yields computer names that do not exist in Active Directory. Could mixed mode Active Directory be causing this? I've included a portion of my script to show that it is probably not a problem with the script. However, since I am using AutoIt to do the search I thought I should post my question here.

_AD_Open()
For $iLine_Count = 1 to $iNumber_Of_Lines
    $sOU = FileReadLine($sOU_List, $iLine_Count)
    $aComputers = _AD_GetObjectsInOU($sOU, "(objectclass=computer)", 2, "name")
    For $iCount = 0 To UBound($aComputers, 1) - 1
    $sSAM_Account_Name = $aComputers[$iCount] & "$"
    $sHostName = StringTrimRight($sSAM_Account_Name, 1)
    $sLast_Logon_Date = _AD_GetLastLoginDate($sSAM_Account_Name)
    $sYear = StringTrimRight($sLast_Logon_Date, 10)
    $sMonth = StringMid($sLast_Logon_Date, 5, 2) ; "string", start, count
    $sDay = StringMid($sLast_Logon_Date, 7, 2)
        If $sYear < 2015 Then
            If StringLen($sHostName) > 3 Then FileWriteLine($sStale_Host_List, $sHostName)
        EndIf
    Next
Next
_AD_Close()

Are this computer accounts that existed and have been deleted? Maybe it's the grace period setting ...

[Robdog1955]

Yes they are. I did not realize that they could still be found if they were deleted. :-)

When a computer is deleted property isDeleted is set to TRUE and the object gets moved to the "CN=Deleted Objects“ container.
Either limit the OUs to search or search for propery isDeleted=False too.

[Robdog1955]

Well, gosh. I guess I need help with the isDeleted property. Here is what I tried.

$aComputers = _AD_GetObjectsInOU($sOU, "(objectclass=computer)", 2, "name,isDeleted=FALSE")

Should be something like this:

$aComputers = _AD_GetObjectsInOU($sOU, "(&(objectclass=computer)(isDeleted=FALSE))", 2, "name")

Just to follow up. Your line of code works perfectly. Thanks once again water!
