'~ SCRIPT NAME: LEGALNOTICE.VBS
'~ WRITTEN BY: JON BRYAN - March 2010
'~
'~ This script should be applied as a machine startup script that applies to all machines in a Domain.
'~
'~ It applies the Legal Text to all machines except those in the "AUTO_BOOT_PC" security group. This is a Security Group in your own Domain.
'~
'~ Before applying this script, remember to remove the 'normal' GPO settings found in:
'~ Computer Configuration/Windows Settings/Local Policies/Security Options -
'~ Interactive logon: Message title for users attempting to log on
'~ Interactive logon: Message text for users attempting to log on
'~
'~ The basis of the Sub was taken from the Scripting Guy's site:
'~ http://blogs.technet.com/heyscriptingguy/archive/2005/01/17/how-can-i-change-the-legal-warning-message-using-a-script.aspx
'~ Although, I have made some changes that affect the layout - initial blank line and indented text (VbTab fails to effect Windows 7 - so spaces
'~ used - works universally) and have made their stand-alone script into a Sub that is called only if the machine is not a member of a group.
'~
'~ UPDATED 07/03/12 - Computers in multiple groups caused the legal text to be written in some cases, as the script evaluated group memberships.
'~ I have sorted this by writing group names to an array, then making a string of the array values, then looking for the string "AUTO_BOOT_PC" within that string!
'~ Additionally the script clears registry values if the computer is in that group. Alternatively, if the computer is not in the group, the registry values are written!
