Windows Server - GPO: Scheduled task to defrag servers

Asked By paulreim

Hello,
I am using this small script to automatically created scheduled tasks
via Group Policy on each one of our servers:

Set WshShell = WScript.CreateObject("WScript.Shell")
Dim fso, d, dc, i, Command
i=0
Set fso = CreateObject("Scripting.FileSystemObject")
Set dc = fso.Drives
For Each d in dc
i=i+1
If d.DriveType = 2 Then
Return = WshShell.Run("echo ""N""|schtasks.exe /create /SC WEEKLY /D
MON /TN Defrag" &i& " /TR ""defrag.exe "&d &" -f"" /ST 15:50:00 /SD
04/08/2008 /RU SYSTEM", 1, TRUE)
End If
Next
Set WshShell = Nothing

The echo ""N"" is necessary because on the second restart, Windows
asks to overwrite the scheduled task. If I omit this, the GPO works
fine the first time, but the after the second reboot, it prompts to
overwrite the task, so I manually have to confirm.....


When I run the script now with  the echo ""N""|, I get an error "The
system cannot find the file specified".

My question is now, what's wrong with the "Wshshell.run"-command or is
there any possibility like a "/N" to confirm that I do not want to
overwrite the scheduled task....

Best regards

Paul,


I'm not a VBScript guy but would know another way to do that. You might
think about it if there are no other responses from smarter VB Script
people:

(option 1) Create a script that does two things: First, it copies a
batch file that runs the defrag. Second, it creates a scheduled task
using schtasks.exe to schedule the task with the first batch. Then
(after the first runthorugh) create a text file somewhere you can check
for. Before the whole script runs, always check for the text file. Itf
the script ran once, the text file is there and you can abort. If the
text file isn't there, run the whole script (as it hasn't run before -
otherwise the file would be there).

(option 2) Use Group Policy Preferences. They come with a Scheduled Task
Preference.

Why is it, you need to defrag your servers, anyway?

cheers,

Florian
