There are four types of scripts that can be configured in GPO.

Computer: Startup & Shutdown
User: Logon & Logoff

Out of these four types, only the user logon script type runs as the user, the other three run as LocalSystem. If LocalSystem rights are not enough, you could incorporate a script that elevates itself using the runas command, however this would be insecure due to the fact that the password would be stored unencrypted in the script, and to run the user would require read access to the script itself thus creating the possibility for users to obtain admin credentials.

What is it you are trying to script that requires admin rights? Perhaps there is a way to accomplish the task with a limited access account.

Thanks for the explantion, I have changed the script to run as Startup in the GPO, but I'm still not sure it is executing on the client pc. I only need to execute a simple batch file that copies a (.ini) file from a shared folder on the server to a folder on the client PC's C:\ drive. I need to check a few client PC's to verify the file has been copied there.

I also need to run a kixtart script using AdminScriptEditor (ASE) as administrator to change the printers on the client pc's from one print server to another. I know I can use the runas command but I'm not sure of the syntax. I'm not too worried about the local admin password being displayed in clear text because this script will only run for a short time, then the lines of code will be deleted.

You can use a vb script to delete the current printer and add the new one. The code is below, and should be able to run with limited rights.

-Source: Microsoft Script repository
http://www.microsoft.com/technet/scriptcenter/scripts/default.mspx?mfr=true

Also, the computer->startup scripts run when the PC boots up, before the logon prompt is displayed. As such it would be hidden from view.

====Begin code to remove a printer connection====
 
Set objNetwork = WScript.CreateObject("WScript.Network")
objNetwork.RemovePrinterConnection "\\PrintServer\xerox3006"
 
 
===end code to remove a printer connection===
 
 
===Begin Code to add a printer connection===
 
Set WshNetwork = CreateObject("WScript.Network")
 
WshNetwork.AddWindowsPrinterConnection "\\PrintServer1\Xerox300"
WshNetwork.SetDefaultPrinter "\\PrintServer1\Xerox300"
 
===End code to add a printer connection===

Yes thank you, I was able to create a GPO that allows me to add Domain Users to the local admin group on their local PCs. I accomplished this by creating a new policy, then selecting Edit. Select > Computer Configuration\Windows Settings\Security Settings\Restricted Groups. Right-click Restricted Groups then click Add Group.

Click Browse > select the local computer, then select the group that you want to add to the local Administrators group (in this case, the "Domain\Domain Users" group)  click ADD, and then click OK.


This security rights change also allows me to execute a GPO Logon/Logoff batch file that copies a (.ini) file from a shared folder on the server to a folder on the client PC's C:\ drive.

It also allows the kixtart script to execute properly as administrator and changes the printers on the client pc's from one print server to another.

I know this is not the best secure way because all users are now local admins on all PCs, however this is temporarily running just long enough for the changes to be pushed out. I then can use the GPOs > Computer Configuration > Windows Settings > Security Settings > File System option to change file/folder perms to allow the Domain Users group modify permissions.
