Group policy and running a .bat file

Hello experts...

I have a question with regard to .bat files and group policies.  Have a log off .bat file that runs defrag and disk cleanup when users log off each night.  The .bat file is located on the file server.  Since removing the user from the local admin group to power users group, I've noticed the .bat file not running when users log off at night.  

So the question is, how do I get the batch file to execute on the local machine using group policies when the user is power user and not an local admin user?

Windows 2000 DC and XP Pro workstations.

The file should execute, but only administrators have the right to defragment disks.  Since the job is running in the user's context, it doesn't have the rights necessary.

It would be better to use scheduled tasks to run your disk cleanup and defrag jobs.  That way they won't slow down logoffs and they will run even if nobody logs in.  Here are some instructions:

You can mass-deploy these scheduled tasks to all of your workstations using the AT command.

Could you expand on the AT command?  I really wanted to avoid having to visit each workstation and setting up the scheduled task.  I was hoping to roll out using GP.

You can view the parameters of the AT command by typing "at /?" at the command line.  As an example, running the following command creates a scheduled task on the target computer which defrags the C: drive at 2:00 am every Saturday.
at "\\targetcomputer" 02:00 /every:saturday defrag c:

Setting up Disk Cleanup to run unattended is a little trickier, as you first have to customize it using the /sageset switch.  See these instructions:

Running "cleanmgr /sageset:5555" and selecting Temporary Files creates a REG_DWORD named StateFlags5555 with a value of 2 under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches\Temporary Files.  It creates a similar entry for any other option you select.

You can use a script to pull this all together.  First create a text file named computerlist.txt.  Enter the names of all the workstations into it, one per line.  Then create a file named schedule.cmd in the same directory and paste the text between the lines into it.

@echo off

set RegPath=HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\VolumeCaches

for /F "tokens=*" %%G in (computerlist.txt) do (

 REM Sets Disk Cleanup registry entries.  Add additional lines here to include other cleanup options.
 reg add "\\%%G\%regpath%\Internet Cache Files" /v StateFlags5555 /t REG_DWORD /d 2 /f
 reg add "\\%%G\%regpath%\Old ChkDsk Files" /v StateFlags5555 /t REG_DWORD /d 2 /f
 reg add "\\%%G\%regpath%\Temporary Files" /v StateFlags5555 /t REG_DWORD /d 2 /f

 REM Schedules Disk Cleanup
 at "\\%%G" 01:00 /every:saturday cleanmgr /sagerun:5555

 REM Schedules Defrag
 at "\\%%G" 02:00 /every:saturday defrag c:



Running this creates a scheduled task on each computer which runs Disk Cleanup at 1:00 am and defrags the C: drive at 2:00 am every Saturday.

Oops, those reg add commands aren't right.  You might have to deploy those using a startup script instead.
