We've had this as well. The culprit really does seem to be the Autodesk Update Manager, or perhaps any application that uses CPU or network heavily.

The driver station seems to be generally vulnerable to any cpu usage on the driver station; just launching eclipse will net us a packet drop. That's usually not enough to get a full disconnect, though.

We had tried disabling the update manager; telling it to not run, but it doesn't seem to respect that configuration setting, as we had the problem come back, just as you've described. And we found autodesk processes running.

Removing every single Autodesk product from the driver station has so far cured the problem, but we're watching it.

Cheers,
