[cobbler] Problem with PXE when DHCP not running on cobbler server

I have a problem with pxe starting a server when cobbler is NOT the dhcp server.  I am unsure why this is but here is the problem. When you create a new server it creates /tftproot/pxelinux.cfg/$MAC_ADDRESS which is fine and works create on my other cobbler systems.  But since this one server is not the dhcp server I get a problem where when the kickstarted server requests its configuration it looks for the hex version of the IP address and not the mac address like in the other cobbler server setup.  Or example..  from my log Mar  7 13:32:13 servername in.tftpd[22679]: RRQ from 172.18.18.55 filename pxelinux.cfg/AC1213C0 It does not look for the mac address ever. Since cobbler does not make the hex version of the IP in this manner it kicks back an error saying it cannot be found. I fix this by creating a symlink from the mac address to the hex version of the IP...  Then it works. This breaks automation for cobbler. Does anyone have any ideas on how to fix this? Thanks!
