What do you mean with 'IT'? Information Technology? The DNS server?
The client? The firewall? Or what?

If the DNS server cannot route packets to the Internet, the problem is
obvious.

Also, you will need to allow incoming DNS responses in order for DNS
resolution to work. Open up incoming to and from 53/udp and 53/tcp and
you may very well see the problem disappear - _IF_ that is the
problem.
