Error MDL shared core library mental ray DBR in 3ds Max 2016

Question:

I'm getting  an error when using mental ray DBR in 3ds Max 2016: Could not locate MDL shared core library.

Answer:

When you try to use DBR (Distributed Bucket Rendering) you will get the following error message: 

Could not locate MDL shared core library.

To help mental ray satellite find this .dll copy libmdl.dll from the main 3ds Max 2016 folder to the NVIDIA\Satellite folder. Note that you have to do this on all the machines that will be used for DBR.
