We are running SBS 2003.

Recently, our business has changed DSL providers and received a new set of
DNS numbers. I set them in the DNS forwarding area of the server and
everyone should be able to go anywhere on the internet, but some sites won't
come up. When I do an "ipconfig /all" it shows our server is the only DNS
server set. DNS is supposed to be assigned to the clients through DHCP. The
only way I can get into all the internet sites is to type the DNS numbers
(including our server) statically into the network config portion of windows.

This isn't normal. What do I need to do?

Hi Carl,

ipconfig/all will not show the DNS servers that are configured as forwarders
because this is a server configuration and not a client-side configuration
setting. The setting should be transparent to clients.

As for being unable to reach certain websites (if I understand you
correctly), the DNS servers you were given work if you input them directly
into TCP/IP settings, but don't work if configured only as forwarders. This
indicates that there is a problem with forwarding. Is it only a few domains
that don't work, or only a few that do work? Have you set the fowarding to
"all other DNS domains"? Have you tried increasing the number of seconds
before queries time out?

Try a different set of forwarders like 4.2.2.1 and 4.2.2.2, or even removing
the forwarders altogether, thereby forcing DNS to use its Root Hints.
If changing forwarders does not work and using root hints does not work
check to see if any external DNS server can be reached from the DNS servers
using nslookup, Dig or Netdig.
Use this nslookup command to see if the Root can be resolved by the
forwarder, and that the forwarder supports recursion.
nslookup -d2 -qtype=ns . <externalDNS>

Under the got answer section you should see this followed by the 13 Root
Servers' records:
Got answer (436 bytes):
HEADER:
opcode = QUERY, id = 2, rcode = NOERROR
header flags: response, want recursion, recursion avail.
questions = 1, answers = 13, authority records = 0, additional =
13

If you do not see the recursion avail. try a different server, this one does
not support recursion.
