Find users who are local admins

Here is a Visual Basic script, which will audit what accounts/groups are members of the local administrator group. I put it as a a logon script. It puts in a shared folder named public a text file with the computer name and users which are in the local administrators group and are not domain admins or administrator:

Option Explicit
Const ForAppending = 8
Dim objGroup, strComputer, objMember, WshNetwork, objRecordSet, objFSO, objFile, strFileName
strComputer = "."
Set WshNetwork = WScript.CreateObject("WScript.Network")
WScript.Echo "Computer Name = " & WshNetwork.ComputerName
Set objGroup = GetObject("WinNT://" & strComputer & "/Administrators,group")
For Each objMember In objGroup.Members
If objMember.Name <> "Administrator" and objMember.Name <> "Domain Admins"
ThenSet objFSO = CreateObject("Scripting.FileSystemObject")
strFileName = "C:\Public\" & WshNetwork.ComputerName & ".txt"
Set objFile = objFSO.OpenTextFile(strFileName, ForAppending, True)
objFile.WriteLine (objMember.Name)
objFile.Close
End If
