Changed the PS2 KVM box for another. Was having trouble with node 1 and the mouse. Everything working now.

Just found out that Windows 7 will work with two CPU's and several cores. Installed Windows 7 Ultimate and all 8 cores are recognized. Will install Windows 7 Ultimate on all 4 nodes. It's easier to use than Windows 2008 Data Center and it supports AVG Free antivirus.

Overall it's a bit slow doing the World Community Grid projects, but I have not have it on all the time either. Just watching the power bill to see the difference.
