Our firewall does DHCP and I set the DNS servers to be the two domain controllers.

DNS used to be set to both the domain controllers and to our ISP providers DNS servers.  I changed it to only the domain controllers and use forwarders for addresses outside the LAN.

I flushed DNS on workstations and did a release/renew on the network card, rebooted and an ipconfig still shows the isp external DNS servers.

I checked the firewall and it only has internal domain controllers/dns servers listed.

How can I get workstations to only show internal DNS servers in ipconfig?

Thanks,

cja

Your suggestion led me to another settings page on the firewall that still had external DNS servers listed.  I made the changes, all good now.  Thanks
