Printer Spooler Stopped Responding

I had this problem in Windows Vista with SLI nVidia motherboard with two graphics cards. The spooler would hang every time I tried to install my printer.

Here's how I fixed the problem:

-Uninstall nVidia Network Management! I'm not sure what this tool does, I believe it is a firewall and I think it cause windows vista services to hang or crash frequently. "It also fixed Host Process Stopped Responding" issue with Vista.

It should work after the above. Post your result here.
