problem with logoff script

Hello, I am trying to make a group of dual boot Windows 2000
Professional machines reboot after a user logs off of them. (We need
this for the dual boot setup).

The procedure I am trying to use is as follows:

1) Create an OU for the machines in the Active Directory, put the
machines in the OU.
2) Apply a GPO that OU. In the GPO under User Configuration=>Windows
Settings=>Scripts=>Logoff add a script.
3) Set the script to \\dc\netlogon\logoff.bat
4) Copy shutdown.exe from Windows Resource Kit to \\dc\netlogon

I am not sure why this does not work. If I run \\dc\netlogon\logoff.bat
from the commandline it works. And the computer reboots.

When I logoff the first time, I see an error message briefly and it
is difficult to read. This is my best approximation:
MOBYSYNC.EXE - Initialization failed (although after googling I think
this is MOBSYNC.EXE)
the dll failed to initialize because windows is shutting down

I also did another test where I started running logoff.bat (which calls
shutdown.exe). As it began the process of rebooting the system. I
clicked Start=>Logoff. The computer logged my user out, but never
rebooted. Is this a synchronization issue?

Thanks in advance for any suggestions/advice,

Rohit

Why not use a VBScript, or JScript using WMI to shut down the workstation...
This would be a call to a local API and you would not require an external
executable... When a workstation is shutting down it is terminating services
and disconnecting user network connections... perhaps your batch file is
getting lost in the organized mayhem... a call to a script will kick off
the script engine as a process on the workstation and should execute cleanly
and without issue...

This should help: save this as a JScript file... reboot.js and modify the
code in the Base Code Area

Thank you very much for this script. As I have some Java programming
experience, it looks a little less intimidating doorway to the Microsoft
scripting world than VBScript.

However, it still does not solve the problem. Executing this directly
reboots the machine. However, executing it as a Logoff script silently
fails :( I am guessing that this problem is solved with Win2k3
synchronized logoff scripts, but I'm not sure what to do with our Win2K
DC.

That is odd... I will see what I can find...

There is a caveat to this script (like any other script)... the logged on
user has to have the shutdown right or it will fail (silently)... check the
permissions on the workstation\server in question... in the mean time I will
do some research...

Good Luck

Thanks again. The user does have permission to shutdown the
workstation. If I run \\dc\netlogon\reboot.js it works.
However from the logoff script it does not work

I was incorrect in saying it will fail silently. I get a similar
MOBYSYNC.EXE error the first time the logoff script (reboot.js now) is
run. After that it fails silently until I reboot the machine.

While a reboot-on-logoff setup is ideal, we may take a different path
completely (such as disabling logoff and only allowing reboot) or
rebooting every dual boot workstation at 4 AM.

Many thanks,

Rohit
