V-ray lights not rendering via Backburner

[Richard7666]

My scenes are not rendering V-ray lights over backburner.

To test, I've just set up a fresh test scene of a teapot, 3ds Max spotlight, and a V-ray dome.
Scene renders fine locally.

But only the 3ds Max light renders over Backburner on my render node.

Any help much appreciated!

EDIT:
Restarting my workstation has resolved this.
It appears to be that the render node couldn't access the networked assets on the workstation, including the .exr I had in the dome light!
Odd that traffic could go the other way, though.
