That's rather strange.

Which tells you that a dhcp server is running and serving out ip addresses.

Sounds like the tftp transfer might be failing.  You do not need tftp-hpa
installed for this to work, you do need tftpd-hpa (note the extra d for
daemon).  tftp-hpa is the client.  If you do 

	apt-cache policy tftpd-hpa

(or look with synaptic) you should see that it's installed.  If not, that's
a problem.  There should be a line in /etc/inetd.conf like this:

tftp        dgram   udp     wait    root  /usr/sbin/in.tftpd /usr/sbin/in.tftpd -s /var/lib/tftpboot

and the output of 
	ps aux|grep inetd
shouldl include a line something like:
root     15508  0.0  0.1   1596   460 ?        Ss   Dec21   0:00 /usr/sbin/inetd

As a test you could install tftp-hpa and then try the tftp download by
	tftp -c get /ltsp/pxelinux.0

(you need to change that ip address to that of your server).  You should
end up with pxelinux.0 in the local directory.

No. Can you be more specific about what you installed.  If there were a
firewall in there that might make some sense but I don't see how installing
software could have this affect.
