Question : T1 Dns

Hello,

We are signing up for a T1 line and one of the questions they as is "Do you have your own dns server?".  I'm not sure if I should answer yes or no.  We have a windows sbs 2003 domain controller running dns for our clients.  Does that mean I answer yes or no?  I feel like I still need access to a public dns server for anything using a static IP.

Actually, Windows SBS and any other flavor of Windows Server family does NOT need an external DNS server.  Your SBS server uses hard coded "root DNS" servers to find out the IPs for externally located (which is why your google.com test worked).  Once found, the IP is cached in the server - use the DNS mmc to see all those queries... you actually might find sites that your employees should not be going to :)

One reason for getting an external DNS is if you are not using DNS internally... in a Windows network with Active Directory (or even without) would be prohibitive.  Do not point your desktops to an external DNS server unless warranted - like a kiosk computer in the lobby.
