Thanks for your post

port 53 isopened for TCP and UDP.

no hardware firewall which is why i want to close all unnecessary
ports.

Windows firewall turned off

Still not working

Is this an internal machine for internal use or for outside ONLY use?
Hosting your external public record on this box, if that is it's sole
intention, you only need the above two ports. However if internal Windows to
Windows communication, then it is a whole different ballpark. You also need
a host of other ports for communication, especially AD domain communication,
such as RPC, Ldap, Kerberos, etc. Keep in mind, an internal Windows client
will initiate a query on a port using UDP >1023, although the response will
be on UDP 53.

So it depends on what this server's over role is.
