A few ideas off the top of my head:
* Since you have a single NIC, perhaps firewall rules are biting you?
Check /etc/sysconfig/iptables
* is TFTP turned on?
# chkconfig --list tftp
if it says it is off, run:
# chkconfig tftp on
# service xinetd reload
* Are the TFTP and DHCP servers now seperate? The clients will try to TFTP
their boot image from the DCHP server unless a "next-server" is specified
in dhcpd.conf
