Local Admin Account Question

[benched42]

I apologize if this has been covered before. I've been writing AutoIt scripts for about four years now and have automated a lot of our program installations. My dilemma is this:

We are about to update our VPN client software and a majority of our users do not have administrative permissions on their laptops and this is needed for uninstallation of our old software and installation of the new. I am quite familiar with how to do this; my problem is that there are two possible local administrator passwords. I can't seem to determine how to write a script that will "test" to see which one is the right password without locking out the local administrator account.

Any thoughts? Thanks in advance.

Here's what I do in similar cases:

RunAsSet("user", "DOMAIN", "p@ssw0rd")
$pid = Run("notepad", "", @SW_HIDE)
If @error Then
    MsgBox(4096,"Invalid credentials", "Please check domain\username password..." & @LF & "Password cannot be null")
Else
    ProcessClose($pid)
EndIf
