it's hard to guess what is error and what isn't in your picture - maybe explain your problem a little bit

Those little rectangular shadows. I f I turn off raytracing for the light that creates the shadow for the bar restraining the guy they go away.

mental ray or maya renderer ?
what happens with the erroneous shadows if you hide the bar and keep raytraced shadows turned on ? basically the shadow cast by the bar looks fine to me
maybe there is some other shadow casting geometry that you aren't aware of
how about depth map shadows ? - same erroneous result ?
finding this kind of errors relies mainly on reducing the number of possible causes

Lestat, these folks are willing to help but you need to give them alot more information if you expect to get any answers.
they're not psychic. :)
so explain your setup from the bottom up.

Sorry for not explaining better. I guess the weirdest thing about this was that it rendered fine at school. When I took the file home it started doing this. I have to run but I'll post a detailed description of the lighting setup tonight. Thanks guys

I can't actually see the picture, maybe it's our ars* firewall here at work..
It sounds like a problem I had the other day which I never actually figure out what it was because of.
I got completely black faces in places where it should've toned out smoothly, I traced it to the translucency node. If i disconnected this from my material it worked fine. Of course there was a reason as to why I put the translucency node there from the start and I would like to keep that node in the network and still get un-buggered shadows.
Maybe I have missed something completely obvious though, or it might be a known problem with a simple solution.
I tried rendering it with both mental ray (no fg or gi) and maya's renderer, just a single light in the scene, same result with both.
