Configure DNS on ASA 5505 v8.2(1)

Hi guys
I would need help on configuringwith ASDM the DNS features of ASA 5505.
I have a static public IP from my ISP and need to pass DNS requests from internal clients.

The ASA also acts as DHCP to provide clients that are configured with IP automatic settings. However the servers (with static IPs) have the ASA as their Gateway and DNS server.

I need the ASA to pass the DNS queries for those servers.

Again, I appreciate the help with this!

You cannot use the ASA as DNS-server. You need to configure your clients to use an DNS-server on internet and open the firewall to allow the dns traffic to pass thru.
