Creating the GPO is straight forward. The question is where to keep the source file. I could place the source file on a file server. Our organization has many locations throughout the state, so I am concerned about the network traffic. The file is only a few bytes in size, but I would like to plan ahead for larger files in the future. Is it ever a good idea to use the SYSVOL share? I cannot find any documents stating the best options for the source file location.
I'd hesitate to put it into SYSVOL, even though it would make sense in this case, technically speaking. Sometime in the future a less knowledgeable admin might follow up on your example with a 1 GB file, or something like that.
For a small file in a not-too-large network I'd probably go for a fileserver, especially since the file is going to be copied only once for each machine in scope of the GPO.
You know, it depends. I'm not surprised that you can't find a best practice.

That makes sense. A 1 GB file with 4,000+ users, would put a strain on our domain controllers. I really did not think SYSVOL would be an option, but it sounded great having the file always available on the domain controller.
