Re: Urgent! New router and big disaster

Hey, I don't get DNS errors. And I'm running single NIC config. Natch. <grin>

sorry, very re-active.

Both NICs should point to his internal IP for DNS. ie. the NIC properties of all members of an Active Directory, even multihomed devices such as this server and my workstation, should point _only_ to an AD integrated DNS server for name resolution, the AD integrated DNS server will then satisfy queries outside the AD by the use of either 'forwarders' or 'root hints'.

If 'CO-DBA-SC-EL' has configured external DNS servers on SBS systems it probably explains some of the wierd errors he sometimes asks of the group.

Both NICs should point to his internal IP. The SBS DNS server, running on the internal IP, will then satisfy external requests via either forwarders or 'root hints'.

C'mon, we're getting close. Don't spoil it.

You're getting close. Since you can reach an external web site by using its IP it means that your problem is now DNS. I don't see how your settings could work. In the TCP/IP properties for the external NIC, you need to specify an external DNS server for DNS, instead of the server's own IP address. You should do that in the CEICW, that way it will set up the DNS forwarding to work correctly. When the CEICW asks you for the configuration for the external NIC, use:
IP Address 192.168.0.99 (See Note 1)
Subnet Mask : 255.255.255.0
Default Gateway: 192.168.0.1
DNS Servers: 192.168.0.1 (See Note 2)

Note 1. 192.168.0.100 looks like an address in the DHCP range of the router. You should give your SBS a fixed external address so you can forward ports to it reliably in the router. I don't have the D-Link doc but x.x.x.99 should be outside its DHCP range. If not pick another one. Why do that if the SBS is the only computer connected to the router? Because some day you might try to debug something else, plug a computer in the router while the SBS is off or disconnected, then plug the SBS back in and discover that the other computer has now been given the address you thought was the SBS's own. Then of course RWW and all those goodies quit working. Play it safe. Use a fixed address outside the DHCP range of the router.
Note 2. Normally the router will forward DNS requests. You may be able to speed things up by specifying the IP address of your ISP's DNS servers instead of the router -- the router will just pass that through instead of actively forwarding.

I checked the binding order and the Server Local area connection is at the top.

I should have been more clear about internet connection..
- when we open internet explorer the company web is shown, when we type in
an address... http:www.google.ca, we get page cannot be displayed. But if I
type the ip address 65.98.45.220 the webpage loads. (this is true for Both
the SBS and client stations)
I just read somewhere in another posting about nslookup.exe, and thought I
would give it a try. I got this..
***Can't find server name for address 192.168.16.2: Non-existent domain
Default Server: Unknown
Address: 192.168.16.2
( I found that in the DNS - clicked my server name and ran the lookup tool)

Check Binding order
------------------------
Right click My Network Places...Properties. Highlight the Internal NIC. Then
select Advanced...Advanced Settings from the top menu for that window. This
will check the bindings.

The Internal NIC should be displayed first followed by the External NIC. If
not, move the Internal NIC to the top of the list.
The Internal NIC should have File and Printer Sharing bound (checkmarked) to
the TCP/IP Protocol.
The Internal NIC should have Client for Microsoft Networks bound
(checkmarked) to the TCP/IP Protocol.
------------------------

Is the Internal NIC at the top of the list?

What is 65.98.45.220? If neother SBS server nor client workstation had
Internet access, how could they view anything at this public (Internet) IP
address?
