What are you trying to accomplish here? What is the external host for? Are you editing DNS?

yes.  I am using an external company to create an on-line catalog for our company.  our domain is 'quakercitypaper.com'  the catalog site is   catalog.quakercitypaper.com and i need to point it to an external ip at their site.  to have the people in my network see the new catalog, i'm thinking i would have to add a  host record on my internal DNS server pointing to that ip adress. (already did that to my external AT&T server and that is fine)

What is your internal domain name? Are you using split DNS? (your internal domain name would be something like quakercitypaper.local if using split DNS.)

OK- and AT&T has your external DNS zone file for quakercitypaper.com - correct?

Then there is nothing you should need to do internally - when a PC within your network goes to catalog.quakercitypaper.com - it should resolve to the external site, just like it does with your www.quakercitypaper.com site.

Did you create a new forward lookup zone on your internal DNS server for quakercitypaper.com? If so - was that there before for some other pourpose? If it wasn't there before - you don't need it.

Yes any computer outside the network can reach it fine (like at home).  but none of the ones inside works (cannot find host).  when i put the entry in the host file on the local computer then it works fine.

No, no forward lookup zone additions.

OK - that looks strange. Can you please try to copy and past that as plan text... Also, it appears that the lat line is cut off... there should be another IP address.

If you type ping catalog.quakercitypaper.com what is the IP address it comes back with?

Sorry - my screen didn't display the code snip in the correct way.

Go into the DNS control pannel on your server and look in the forward lookup zone for your quakercitypaper.local domain. do you have a record for 'catalog' or 'catalog.quakercitypaper.com' in there? Did you remove it?

After you do remove it, right click on your server name in the DNS tool, select clear cache, then go to all tasks and select restart.

From your workstation, at the command prompt, type in 'ipconfig /flushdns'

Then do the nslookup again.

catalog.quakercitypaper.com should come up with an ip address of 208.91.144.129.

If it does - then you are in business.

yes, strange.

I noticed in your last comment - you pinged the wrong address... Does it resolve an IP address if you use the correct name? catalog.quakercitypaper.com ?

if you try the NSlookup from your server - do you get the same result?

Have you setup DNS forwarders on your DNS Server? If you have - can you confirm that the DNS forwarders are the correct DNS server supplied to you by your ISP?

yes the server does the same.  checked the dns forwarders and I only had one of the AT&T's dns in there.  I put the other one in and redid everything and got the same result.  I'm going on their web site to make sure its right, but all other URL are resolving fine.  Thanks....

what happens if you do an nslookup of your company website? www.quakercitypaper.com ? Are you able to access your website normally?

But 10.10.1.34 is an internal IP address.

Do you have a forward lookup zone on your SBS DNS server for quakercitypaper.com?

OK. Where on your network is the DNS zone for quakercitypaper.com? From what I've seen you must have that domain somewhere on your internal network.

The reason you have to have it somewhere on your internal network is that external hosts are pointed to an external IP address when viewing that site, but internal hosts are directed to an internal IP address. So you must have a copy of that zone loaded somewhere on your internal network. Do you have another DNS server somewhere on your network?

IF you have all of your quakercitypaper.com hosts pointing to an internal address - that is setup on a DNS server - perhaps not your SBS server (but I cannot imagine where since the default DNS server on your network is the SBS server and if it isn't on that server then the SBS will check your forwarders (external) and then the internet root servers.

Can you tripple check - on your SBS server - open DNS then open Forward lookup zones and tell me what you see there?

Thanks.

I put some print screens in word (attach).  I'm not sure what you mean. the only internal DNS is the SBS server.  people outside get in through the external ip i have setup (AT&T) and nat table in the router.  thanks for hanging in there with me......

what kind of firewall do you have?

In DNS, if you right click on the DNS Server (QUAKERS2003), and select properties, and go to forwarders, can you tell me what you have set there?

All right !!!!  that was it..   when i went in there before I saw i had an internal ip address from my previous dns server (an IBM iseries).  I deleted it and put in the sbs server and applied, but didn't notice it didn't take my applied.  I went back in now and it was the same as before.  this time i deleted all internal forwards and now only external dns is there and restarted and everything is working.  Again thanks for staying with me and thanks... :)     Dean
