Multiple subnets with one DC running DNS service

I have just put in an MPLS network between 7 sites. All sites have the
server in the home office listed as their DNS server. However, they
can not ping/access the internet via host name. If I use the IP
address I can ping and surf the net. What do I need to do on the dns
server to allow the other networks to get dns?

DNS server is 192.168.10.10

I have 6 other networks, with the primary dns server set to
192.168.10.10. These networks are
192.168.11.x
192.168.12.x
192.168.13.x
192.168.14.x
192.168.15.x
192.168.16.x

Thanks for all the help I can get.

Users in each site use *only* their own DNS at their location.

The DNS Server then has the ISP's DNS entered into the Forwarders List in
the DNS Service's Configuration. The DNS machine must be allowed by whatever
is being used as a Firewall to be able to make outbound DNS queries tot he
ISP's DNS. It is a good idea to limit this access to only the DNS machine
and not the Users,...so as to trap any machines that has rogue DNS entries.
You could also have the DNS machine use Root Hints instead of the ISP's
DNS,...but using the ISP's DNS is the most common, and probably, the best
practice.
