2003 Server DNS Problems

[Robroy2003]

Hi all,
Having a DNS Problem. My domain is called say fred.com. I have 3 servers running active directory and 2 of the 3 running DNS. Fred1, Fred2 and Fred3.fred.com
If I ping from a workstation fred.com I might get a reply from any of the 3 servers. When I look in DNS I have a record for (same as parent) with the ip address of the respective server and the sole name of Fred.com. If I remove the 2 entries that are not running IIS then all id fine for 1/2 hour until DNS rebuilds the records. Let's say fred1 is running iis and has my Public Web site and Intranet site running on it. I have an A Record for intranet.fred.com and the ip of the machine running iis but that doen't mean it's gonna work. Any idea's here?

Thanks

Could you please restate your question? I'm clear on your servers but not about what you are having a problem with.



I hope you find this post helpful. Please let me know if it was.

Ok,here we go.. My local domain is Fred.com, as is my internet domain. When my local users try to go to

http://www.fred.com,

dsn is telling it 3 differnt ip addresses, depending on which time you hit it. This is causing havoc. Also, mail.fred.com, my mail server on the local domain and the internet domain does the same thing. Even though I have an A Record for mail pointing to a particular address.

I'm sorry I'm not very clear, Been a long week...

Thanks

OK, I think I get you now.

You need to set an A record for

http://WWW on

your local DNS.

Next, make sure that your clients only have the local DNS server listed in their IP properties.

On your DNS server, have it point to itself for DNS, do NOT configure external DNS servers in the TCP/IP properties.

Finally, on the DNS Server in DNS Properties, configure your ISP DNS servers on the Forwarders tab.

If you are not hosting your public web site, you might want to consider using the Domain Rename Tool to change your local domain from Fred.com to Fred.local just to avoid such confusion.
