.SYNOPSIS
ScriptSentry finds misconfigured and dangerous logon scripts.

.DESCRIPTION
ScriptSentry searches the NETLOGON share & Group Policy to 
    1) identify plaintext credentials in logon scripts
    2) identify admins that have logon script set 
    3) identify scripts and shares that may have dangerous permissions
