I have similar problems in C3HF1 with IES lights sending to the renderfarm when the folder my project was in, had a special character such as a french "é" in the name. On my own workstation all renders were fine, and on renderfarm without IES. I don't think it was specifically related to corona then, but rather the archiving plugin. Spent lots of money figuring it out that was the reason my renders came back without the IES lights...
I learned the hard way then , but now a warned man... something :) ...
