Windows Domain access from DMZ

Have a web server in a DMZ. We can access web pages on the web server from the internal net and the web server can see a database server on the internal side. The web server can ping the DC, but windows authentication does not work. I need to be able to browse files on the web server in the DMZ.

access-list inside_nat0_outbound extended permit ip 10.4.0.0 255.255.240.0 172.31.4.0 255.255.255.0

access-list DMZ_outbound extended permit ip host 172.31.4.127 host 10.4.0.12 (IP of DC)

Is there something else i need to add so that the web server in the DMZ can authenticat to the DC?

Thanks, Bill

I joined the the server to the domain prior to moving it into the DMZ.

I will look at the ports and give that a try.
