I use Roxio on a network with a firewall. No software updates allowed. When I launch Roxio Business v10 it takes FOREVER to load. If I disable my NIC it lauches as it should. I assume it's checking for updates. Is there a registry hack I can use to disable this feature?

The software was not designed to run in a network environment. If it takes disabling your NIC to do it, then there is your hack.

You can also click on the Roxio 10 icon, on your desktop, click on Tools, then General, and uncheck the box to the left of Check for updates.
