Copying a file to multiple workstations

[prosportal]

Long story short, I'm needing to copy a small software auditing application to the local partition on about 320 workstations where I work.  I have AD admin rights so I was using PStools with a computer list, but for some reason ps tools is acting flaky. Are there any other popular known methods to pulling this off other than c$ to every workstation?

Thanks.

Is this a corporate setup with a domain if so why not setup a login script to download the file from the server when a user logs on. Then it will copy the file the next time someone logs on.
