Hi Guys,

We have an issue where our domain name is iradio then we have an A record  79.140.211.194 that resolves to mail.iradio.ie so in the office i would love to be able to resolve 192.168.20.1 to mail.iradio.ie but because the domain name is called iradio it wont work when i put an entry into DNS

Is it possible to change a domain locally and active directory? so i cant get it to resolve to 192.168.20.1 to mail.iradio.ie ?

So it sounds like you are using the public DNS to resolve your mail server.

Couple questions for you what is your active directory domain name? Is it Iradie.ie or something else?

You may be able to create a new zone within DNS so that you can enter your local IP address of your mail server.

If your internal domain name is iradio.ie you should just be able to create an internal DNS record pointing to the lan address of your mail server.

That looks correct with the new zone setup, but I'm uncertain how the single label domain name might affect things (they really should not be used).  Make sure the client is only configured to use the internal DNS servers, and clear the cache on the DNS server.

If you think about it the answer should be fairly evident.  Do you have a record for "www" in your iradio.ie zone?  When a zone for a particular domain is present on a DNS server, the DNS server thinks it knows everything about that zone.  Simplest fix is to add the record in that zone (there's a couple variations, but I don't want to add to any confusion).
