Need VBScript to list disabled accounts - vbscript

Question

The following script check local computers for inactive (90 days or more) accounts and disables them. The script works fine, but it lists all the disabled accounts every time is executed. I only need it to list the accounts that have been disabled the day is was executed.
Option Explicit
Dim objNetwork, strComputer, objComputer, objUser, dtmLast, objGroup, ObjGroupDict
Dim FSO, OutPutFile
Set FSO = CreateObject("Scripting.FileSystemObject")
'1 = reading, 2 = writing, and 8 = appending. The third parameter is a
'boolean true means a new file can be created if it doesn't exist. False
'means a new file cannot be created.
Set OutPutFile = FSO.OpenTextFile("C:\Test\Result.log", 8, True)
'Bind to the local computer.
Set objNetwork = CreateObject("WScript.Network")
strComputer = objNetwork.ComputerName
Set objComputer = GetObject("WinNT://" & strComputer & ",computer")
'Enumerate all users.
objComputer.Filter = Array("user")
For Each objUser In objComputer
Set ObjGroupDict = CreateMemberOfObject(objUser)
If ((Left(objUser.Name,3) <> "au_") And (CBool(ObjGroupDict.Exists("Administrators") = False))) Then
'Trap error if user never logged in.
On Error Resume Next
dtmLast = objUser.lastLogin
If (Err.Number <> 0) Then
dtmLast = #1/1/1970#
End If
On Error GoTo 0
'Check if last logon was more than 90 days in the past.
If (DateDiff("d", dtmLast, Now()) > 90) Then
'Disable the user.
objUser.AccountDisabled = True
objUser.SetInfo
OutPutFile.WriteLine(Now & " " & strComputer & " " & Wscript.ScriptName & " " & objUser.Name & " " & "Disabled")
'MsgBox objUser.Name
Set FSO = Nothing
End If
End If
Next
Function CreateMemberOfObject(objUser)
'Given a domain name and username, returns a Dictionary
'object of groups to which the user is a member of.
'Inputs: objUser - User Object
Set CreateMemberOfObject = CreateObject("Scripting.Dictionary")
CreateMemberOfObject.CompareMode = vbTextCompare
Dim objGroup
For Each objGroup In objUser.Groups
CreateMemberOfObject.Add objGroup.Name, "-"
Next
End Function

Answer 1

You're disabling all accounts whose last login was more than 90 days ago, even if the account already is disabled. Add a condition that matches only accounts that are not disabled, and the code will do what you want:
If DateDiff("d", dtmLast, Now) > 90 And Not objUser.AccountDisabled Then
...
End If
