I was able to get hqueue setup and see clients. The problem is when I submit a job. Each client seems to attempt to render, however they all fail except for the machine that is the server. That one seems to render its frames. Any ideas on what may be happening here?

Hard to tell from here, can you post any info about the messages you were getting from the clients? What OS are you using?

If your HQueue shared directory is on the same machine as the server, then I would guess the clients don't have the shared directory mounted.
