Silent client update from Office2000Pro Admin Point suppress reboo

[Steven]

I am using the following command in a BAT file to silently update MS Office
2000 Pro clients from an Administration Point on a server.

msiexec /i F:\install\office2000pro\data1.msi REINSTALL=ALL
UPGRADEWITHRECACHE=TRUE REINSTALLMODE=vomus /qn

The update works fine but occasionally a computer will automatically reboot.
I have tried to find a switch that will suppress any reboot that may be
needed but have had no luck. Does anyone know of an msiexec switch I can use
for this purpose? Any help would be greatly appreciated.

Thanks.

Steve
