Ok, probally a simple fix just now sure how to do it. Here in the office we own XYZ.com and it directs to our local server. We have several subdomains office.xyz.com and office2.xyz.com they work fine outside of our local office, but when I ping them from inside xyz.com network it always returns the ip address of the xyz.com server. How do i fix this? Thanks

How is DNS resolution configured across parent and child domains? Note that DNS configuration across parent and child domains is recommended to be setup this way Parent to Child - Delegation - http://support.microsoft.com/kb/255248 Child to Parent - Conditional Forwarders - http://technet.microsoft.com/en-us/library/cc757172(v=ws.10).aspxSachin Gadhave MCP, MCSA, MCTS

Kind of lost me there. I have one domain that points to my one server. I use freedns and setup subdomains that point to different locations. They work fine everywhere except on my local network. I have server 2008 r2 if it matters. It is hosting my website.

Hope you're referring to domains and sub domains in the context of active directory parent and child domains? My understanding is that you have a parent domain xyz.com and child domains office1.xyz.com....office2.xyz.com (different locations)etc. in the same AD forest, correct me if I'm wrong. Or you're referring to domain controllers with names xyz/office1/office2 in the same domain, please clarify. You domain controller for xyz.com domain is also running DNS server for xyz domain and rest of the domains run DNS server for their own domains. These domains are separate administrative divisions hence DNS name resolution needs to be enabled across them using delegation/conditional forwarders. Hope you follow me here.

I only have one server at my office. This might be easier with actual domains. ct1.us points to my server at my office. I use freedns.afraid.org to point all traffic for ct1.us to my server at my office. I set up subdomains ie. condo.ct1.us to point to different ip addresses. I can ping condo.ct1.us from everywhere but my office. My main servers ip address is 192.168.1.10 when i ping condo.ct1.us from my server or any computer at my office I get my servers ip address 192.168.1.10 not the public ip address that i get otherwise for condo.ct1.us My server in my office is the dhcp and dns server for my small office network.

Looks like there is a DNS host record for condo.ct1.us in your local DNS zone database. When you query hostname it will be first looked in the DNS cache if it's not found there then the local DNS server will be queried and at last the query will go to the internet DNS server (when internal DNS server doesnt have an entry for that host). in your case the local DNS server returns the query which means there is entry for condo.ct1.us in the local zone database. You will have to remove it and rename the hosts file so that the query goes outside to the internet. Open DNS management snap -in and look for Host record for condo.ct1.us that points to your local server and delete it from there. Also rename the hosts file under C:\windows\system32\drivers\etc folder. Once this is done , run ipconfig /flushdns & ipconfig /registerdns on the server. One question - have you set root hints or forwarders for internet DNS servers outside of your network? Also please post ipconfig /all from your server here. Sachin Gadhave MCP, MCSA, MCTS

I opened up the DNS Manager and did not see any host record for condo.ct1.us inside of Forward lookup zones Under Fowrwarders in the properties of my server inside the DNS snap in I have one forwarders it is 8.8.8.8.

No Host record for condo host? Please disable IPv6 if you dont use it - http://support.microsoft.com/kb/929852 Under forwarders put a conditional forwarder for condo.ct1.us and specify the IP for that DNS server. Also you add a maunal entry for this subdomain in the hosts file, add this line to the hosts and save it. x.x.x.x condo.ct1.us x.x.x.x will be the ip address for that domain DNS zone

I could not fine any host record for it. Is the DNS manager where I needed to look? I can not add a manual entry for this sub domain as it has a dynamic ip address.

Yes look in DNS manager. What happens when you explicitly specify external DNS server IP under NIC properties of this server? does the query go outside?Sachin Gadhave MCP, MCSA, MCTS

When I changed the nic to 8.8.8.8 instead of 127.0.0.1 it pings condo.ct1.us correctly.

If I return the nic to 8.8.8.8 i get a response from ping condo.ct1.us

In that case Configure Conditional Forwarder for condo.ct1.us Look here for instructions- http://msmvps.com/blogs/ad/archive/2008/09/05/how-to-configure-conditional-forwarders-in-windows-server-2008.aspx This should fix your problem.Sachin Gadhave MCP, MCSA, MCTS

condo.ct1.us has a DYNAMIC IP address. Looks like the directions want me to put in the static ip off condo.ct1.us

Looks like you misread me. I want you to specify the public DNS address 8.8.8.8 against condo.ct1.us in conditional forwarders.Sachin Gadhave MCP, MCSA, MCTS

Do I need to select store this conditional forwarder in active directory and rpelicate it to all dns servers in this forest? When I hit ok I get an error DNS A problem occurred while tryting to add the conditional foorwarder. a zone configuration problem occured. This is what i am trying to do So let me understand this. The DNS server you are setting a forwarder to is hosting a zone called, example.com. You are then attempting to create a conditional forwarder to a child domain such as, child.example.com.

As I know this is the only DC/DNS server you have hence there is no replication. conditional forwarders are set to route DNS query based on the domain name you specify, any requests for that DNS suffix will be forwarded to that particular address. If you dont want that you can also route all external requests to internet DNS server which will not require any replication as the setting is on the server node. Please add internet DNS server address directly under server properties so that all external requires get routed to internet DNS. Refer to screenshot below- Sachin Gadhave MCP, MCSA, MCTS

8.8.8.8 was already in there. Added my isps as well and still get ping request could not find host condo.ct1.us

Give up....

Anyone else got any ideas?
