Wedge,
Make sure you have the CPU to RAM Ratio set to 1:1
As for networking the two computers, make sure you have something shared on each machine, if not, there is nothing to see.
A little more detail on how you have setup the network protocols would help. (Otherwise we would need to go though every step on setting up a network.)
Take Care,
Richard
P.S. Here is an
