Okay, I'm stuck.

I've got 1 file, I'm trying to render it on 3 machines. The only difference I've made is in the Render Globals I've divied up the frame numbers, so CPU 1 is rendering 1-100, CPU 2 is doing 101-200, etc.

Well, CPU 2 is working fine. It's cranking 'em right out.

CPU 1 and 3 are hanging up on the first frame they try to render. It starts, it even creates the file (1k), and then it stayed hung up on 0%. I've let them sit and they just stay there.

I'm at work, so the 3 machines I'm using are identical in performance/setup.

I'm not getting any errors, so I have no idea what's wrong. All three machines render just fine with Maya Software, but 1 and 3 get hung up with MR. What gives?
