How do I stop the built in Infiniband Subnet Manager from loading at startup?

I have setup a new DSS7 box and every time I boot the box my Infiniband network starts throwing errors. All my existing Windows Servers start dropping connections to the Infiniband fabric.

I am thinking it is the built in subnet manager so I want to disable it to see if the problem is resolved if SM is not loaded.

Thanks,

Todd
