HOSTNAME not being applied

I have set up my hostname in dhcp and my dns server, but I cannot get the client to pick up the hostname that is listed for the ip.

IE. 10.32.23.4 hostname should be client4

Anyone know why?

It was working before and just stopped working

have you tried using the tools "host" and "dig" ?

check your /etc/resolv.conf on the client

Can you ping your nameserver from the client?

What are the contents of your client's /etc/nsswitch.conf?
