force ownership of an executable / batch file ?

I am running windows 2000 server with IIS 5.0 ..

I have an asp page that calls a batch file (myBatchFile.BAT)
which in turn calls an executable (wpuba.exe) and that executable calls another executable (framemaker.exe) ...

flow of operations
( aspPage-> myBatchFile.BAT-> wpuba.exe->framemaker.exe )

now when I run myBatchFile.BAT directly (by double clicking it)
then the processes in the task manager runs under "Administrator" and both executables run fine ....

but when I have the asp page call the batch file..then the processes (in task manager) run under the "SYSTEM" user and the framemaker.exe hangs and cannot be killed ...

I have changed IWAM_machinename and IUSR_machinename read & execute perms .. w.r.t the executables and changed the "application protection" to low (IIS process) ..but still have the same problem... .

i think it might be a permissions issue ... is there something that I'm missing ? ...

can I force the user of the batch file to be "administrator" ?

if anyone has any ideas ... I'll dance with joy to hear them ..

thanks

matt
