Hello Mike,

There is a problem when I bond my switch ports and bond my server  
ports. I am leaning towards the problem being the modes between the  
two. When I remove the bond on the switch it works when I put it back  
in place it can't communicate any longer.
At this point I am sure I have everything right and am now dealing  
with hardware rather than software issue.
Thank you for all of the help and for laying it out clearly in your  
first email to me, that definitely cleared my confusion up. I think my  
biggest problem came from the bond on the switch and the server. I had  
built the bond on the server by hand multiple times but could never  
ping out. So I was chasing the wrong rabbit down the wrong hole. :)

Thanks again,

Jon
