Yewston, Well, after I posted my question, I had to stop and think about what cable I was using. :) I do not recall if it was 'straight thru' or 'rolled' ethernet that I used between my two nics. I believe it is the straight, unfortunantly, I am in the process of packing up and moving to another city so all my toys and manuals are put away. Good point about Bryce not installed on the second PC, a person only needs Lightening installed on the second PC. I have used several different setups, dual 866, single 733, and single 2.66 all with Win2k and have not noticed that it made much difference which PC ran Bryce and which PC had Lightening on it.
