Par défaut DNS problem


Hi
I am able to view www.membersedgellc.com from itnernet. However, it is
not viewable from our office net (intranet). Traceroute shows only the
gateway 192.168.1.253 and the external IP 209.178.198.245.

Also the internal DNS server (192.168.5.10) resolves the
admin.scholasticfundinggroup.com correctly but fails to resolve
epcs.scholasticfundinggroup.com. Both these sites are registered with
external DNS servers (e.g. check with dnsstuff.com). In fact, the
internal DNS server resolves epcs.scholasticfundinggroup.com to
192.168.5.58 which is obsolete because I changed the IP to
192.168.11.58. I don't know why DNS server can't update itself. Or do I

need to set them up? Here are the external DNS hosts (forwarders)
209.178.200.2, 209.178.223.4, 209.178.200.4

Thanks

Correction: the gateway is 192.168.11.253

Thanks

209.178.198.245 is the address of www.membersedgellc.com. Are you
redirecting that address to an internal server on your firewall? Many
firewalls don't let internal users access the public IP of a redirect;
NAT only works when going in-to-out or out-to-in, but not in-to-in. You
need to put the private IP on your internal DNS server.

Where did you change it? If you just changed the address on the server,
you still have to update your internal DNS.

How do I put the private IP on the internal DNS server? It is a windows
2000 machine.

The following services are running on my Windows 2000 server:

-DHCP Client
-DNS Server
-DNS Client

How do I add "A" records? I checked properties under each of the above
and couldn't find the button to add "A" records. Many thanks for your
.

Assuming you're running bind read up on split views.

Launch Administrative Tools -> DNS Server and add the domain.
