You can use the same profile for all systems, you just need one Cobbler 
system object for each system.
You must fill network data in each Cobbler system object.

What Linux distribution are you trying to install? I suppose you are not 
providing
system network setup in kernel options, in which case the installation 
kernel will
use DHCP to setup network. I have already seen this non-intuitive error 
message
in RHEL/Fedora installations, its root cause is that DHCP was unable to 
get network
information from DHCP  server after netbooting and before starting OS 
installation.
