Startup Script parameters

We have a Win2k3 domain with XP clients. We have a batch file that runs fine either manually or by placing it in a users Startup folder. We want to use the batch file in a GPO Computer Startup Script. We have copied the script to the correct path and defined it in the Script name field but, it does not run. The gpresult shows the GPO is applied to the computer. It seems like the Script parameters is where we are having the problem but we don’t know what to do next.

Here is the detail of our batch file:
msiexec /x {00000409-78E1-11D2-B60F-006097C998E7} /qn /norestart /l*v C:\Office2000uninstall.log

Look forward to a response and thanks in advance.
