I recently installed a Cisco 877 ADSL Router connecting to our ISP over PPPoA.
We have a Windows SBS 2003 running DHCP and providing DNS to all the clients on the domain.
Since installation, internet address look-up has been slow and I think it's the DNS setup within our LAN...
DHCP allocates the client DNS server, as:
18.104.22.168 (Global - ISP)
The Router Configuration File is set as attached.
Should the Router and/or be set with the Primary DNS of the SBS Server or The ISP DNS servers?
