[cobbler] Server building in a loop

Hello, I am new to cobbler and really like what I see. However, there seems to be a problem with the provisioning of my servers. I have been able to get my redhat/suse servers to build just fine but they seem to go back into a loop after rebooting. They have been setup to pxe boot first and I have the pxe_just_once setting set to 1 in /etc/cobbler/settings file but I never see the "Netboot Enabled" option changed to False after a redhat server has been provisioned. I also added $SNIPPLET('kickstart_done') at the very end of my kickstart file and am using the latest stable release (2.4.0-1). Is there something I am missing here? Do I need to do anything else to get this to work and stop building the server over and over again? If I manually change the "Netboot Enabled" option to false for this server then the server does not rebuild upon reboot but I need to find a automated way to achieve this. Also to point out that my DHCP server is external and not managed by the cobbler server. Any help would be greatly appreciated! Thanks, -J
