Delete Local User Accounts by OU

Posted on 2011-02-24

Good Day,

After performing an audit on all our Workstations. I have discovered some Local Administrator accounts which do not follow our normal build standard naming convention. There are around 150 workstations with this misconfiguration. I would like to script their deletion (the proper Admin account also exists on these machines, renamed correctly via GPO). Can someone help me with the script please. It should read the machine names in from an OU in Active Directory, connect to each machine and delete the 2 rogue accounts if they exist.

I already have some code, thanks to a previous post, which reads in machine names from AD and outputs a list of Local Group members to a .csv file. Please see below.

rrGroups = Array("Administrators", "Remote Desktop Users", "Users")
strOutput = "LocalGroupMembers.csv"

Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objOutput = objFSO.CreateTextFile(strOutput, True)
objOutput.WriteLine """COMPUTER"",""GROUP NAME"",""MEMBER NAME"""

Set oConn = CreateObject("ADODB.Connection") 
Set oCommand = CreateObject("ADODB.Command") 
oConn.Provider = "ADsDSOObject" 
oConn.Open "Active Directory Provider" 
Set oCommand.ActiveConnection = oConn 
oCommand.Properties("Page Size") = 1000 
oCommand.Properties("Searchscope") = ADS_SCOPE_SUBTREE 
sOU = "'LDAP://OU=ouServers,DC=example,DC=com'"

oCommand.CommandText = "SELECT Name, ADsPath FROM " & sOU & " WHERE objectCategory ='computer'" 
Set oRecordSet = oCommand.Execute
Do Until oRecordSet.EOF
	strComputer = oRecordSet.Fields("Name").Value
	If Ping(strComputer) = True Then
		For Each strGroup In arrGroups
			'WScript.Echo "List of member of local Administrators group for " & strComputer
			On Error Resume Next
			Set oLocalAdmins = GetObject("WinNT://" & strComputer & "/" & strGroup) 
			If Err.Number = 0 Then
				On Error GoTo 0
				For Each oLocalAdmin in oLocalAdmins.Members 
					objOutput.WriteLine """" & strComputer & """,""" & strGroup & """,""" & oLocalAdmin.Name & """"
				objOutput.WriteLine """" & strComputer & """,""" & strGroup & """,""Error " & Err.Number & ": " & Err.Description & """"
				On Error GoTo 0
			End If
		objOutput.WriteLine """" & strComputer & """,""" & strGroup & """,""OFFLINE"""
	End If

MsgBox "Done. Please see " & strOutput

Function Ping(strComputer)
	Dim objShell, boolCode
	Set objShell = CreateObject("WScript.Shell")
	boolCode = objShell.Run("Ping -n 1 -w 300 " & strComputer, 0, True)
	If boolCode = 0 Then
		Ping = True
		Ping = False
	End If
End Function

Hi, if you actually know the name of the accounts you want to delete, the easiest way to get rid of them would be to add a StartUp script from a GPO, with the following code in it:

On Error Resume Next
Set objNetwork = CreateObject("WScript.Network")
arrUsers = Array("AdminWrong", "RDWrong")
Set objComputer = GetObject("WinNT://" & objNetwork.ComputerName & "")
For Each strUser In arrUsers
   objComputer.Delete "user", strUser

Open in new window

That way, the accounts are deleted by the local SYSTEM account, and if they don't exist, nothing happens.

Hi Rob,

That is much better. It will catch every machine as it logs on. Rather than me running a script multiple times trying to catch machines while they're online and still missing a few.

I'll give it a test and post back the results.

Works great! No modification required. (other than inserting the usernames of course) ;)
And copy the script to the Netlogon or Sysvol share so it's available to all machines.

Merci Buckets!!

One question. My Manager is sure to ask.

If we want to do the reverse, delete all user accounts NOT defined in arrUsers. Can you show me the code for this please.

Hi, that get's slightly more complicated because you need to enumerate each group for their members, and if the user is not in the array, then delete them.

One way, however, that would cover both scenarios at once, is to use Group Policy Restricted Groups:

This ensures that certian local groups have only the specified members, but it doesn't *delete* the accounts....if you do want to delete the accounts, I can knock up the other version for you.
