I have a big problem in rendering scenes. Sometimes it seems that I go well, however, not all renders nothing. Sometimes they come out errors such 0xd000 / 0xd300. but in any case are four days that I try but I could not render anything

My configuration is this:
1 Server with "WinServer 2012R2"
1 iMac Client OSX El Capitan
1 MacPro Client OSX El Capitan
I configured and installed all. Clients are seen correctly by the server, but when I launch the render "Renderman or Mental Ray" the problems are many. I would ask for a few things:
- the folder with the Maya projects "/ documents / Maya / Project" must be on the server or leave them on the client ???
- both Renderman for Mental Ray renderer as I'm using "Maya Scene" is correct?
- i have to render from the server or from the client submitter?
PLS Help me and sorry for my english
