Looking for options to copy files to large number of devices.

Just looking for options that might be out there.

We have SCCM but there have been issues in the past where files weren't available quickly enough.

I've got PowerShell scripts that do what I want, but I was wondering if there are other server apps that can be quickly configured to copy files out to 1000+ Windows devices immediately or at a scheduled time. It would help if it allowed copying to groups of devices as well as blasting to all of them.

Thanks.
