Logon script to change password failing "permission denied"

I have a script that i'm trying to run on our domain as a log on script.  

the first script references the second script.

Script 1:

'LocalAdminPasswordChange.vbs
'******************************

' NAME: Local Admin Password Change
'
' AUTHOR: Tyler Brill

' COMMENT: This script is designed to be used as a login script
' that will change the Password of the Local Administrator
' on the computer that it is run on using creditials from a
' specified user account and password.
' NOTE: It calls the ChangePassword.vbs from a specified path in this
' script. If the ChangePassword.vbs file is not in the path, Then
' the script will not change the local admin password.
'==========================================================================
'==========================================================================
'********** IMPORTANT INFORMATION **********************
'* Because .vbs files are easy to view and this one contains a clear text
'* password it is important to use the Microsoft Script encoder to keep
'* sensitive information unavailable to someone using a text editor.
'* The encoder can be found at:
'* http://msdn.microsoft.com/library/default.asp?url=/downloads/list/webdev.asp
'* It is a command line tool FYI.
'==========================================================================

' ** First we set the variables for the script ** '
Dim WshShell, objFSO

' ** sUser is the Username
' ** sPass is the Users password
' ** sCommand is the command that you want run
' **
' ** You can replace these string variables to any user/password/command
' ** combo that you need to run on a pc.
' ** NOTE: If you change the sPass field be sure to retain the
' ** quotes and the ~ at the end of the actual password, it
' ** is the carriage return character.
sUser = "Administrator@orbitec.int"
sPass = "****************~"

' ** USAGE: sCommand = "wscript <path_to_scripts>\<your_script_here.vbs"
' ** or you can write in any command that needs to be run under
' ** a specific users account.
sCommand = "wscript \\pluto\software\change\changepassword.vbs"

' ** This is where we setup the working environment for the script to run in.
Set objComputer = CreateObject("Shell.LocalMachine")
Set WshNetwork = CreateObject("WScript.Network")
Set WshShell = CreateObject("WScript.Shell")
Set WshEnv = WshShell.Environment("Process")
WinPath = WshEnv("SystemRoot")&"\System32\runas.exe"
Set objFSO = CreateObject("Scripting.FileSystemObject")

'** Here we will check to see if this script has run on this computer.
'** If the file exist then we will end the script.

If objFSO.FileExists("C:\ChangeScriptLog.txt") Then
WScript.Quit

Else
' ** Here we open the Finished.txt and append the name of the computer
' ** that was just changed and the date it happened.

Set objTextFile = objFSO.OpenTextFile("\\pluto\software\change\Finished.txt", 8, True)
objTextFile.WriteLine(objComputer.MachineName) & " " & Date() & " " & Time() & " " & (WshNetwork.UserName)
objTextFile.Close

' ** Here we write a .txt file to the root of c: for verification that the script
' ** has been run on this computer.

Set objFile = objFSO.CreateTextFile("C:\ChangeScriptLog.txt")

End If

' ** This is the meat of the program and where the actual command is run.
rc = WshShell.Run ("runas /noprofile /user:" & sUser & " " & Chr(34) & sCommand & Chr(34))

' ** This gives the command window the time to open.
WScript.Sleep 900

' ** This will grab the active command window to send the password to.
WshShell.AppActivate(WinPath)

' ** This will send the password to the waiting window.
WshShell.SendKeys sPass

WScript.quit

objUser.SetInfo

If I run the script while logged in as the domain administrator the script runs successfully.  However logged in as any other user I get the message shown in the screen shot attached to this post.  Line 69 is the line that writes to the output log file on the server.  I have no idea why permission is denied here.  Any ideas?
