Are you trying to ping the servers in the DMZ by name or by IP address? If it works OK by address then probably you will have to put hosts files on all the local PCs or have an internal DNS server.
Can you give us a detailed IP map?
You say that you can't ping, but can you do anything else? Could it be that you need routes set up on the firewall?

you should list a map here of how things are layed out and also post the rule base. That would make it very easy. Without them everyone will just be making guesses.
Check your rules, and make sure that ICMP packets are passed from the DMZ BACK to your internal network.
