domain changing

By callupchuck ·
I have set up a LAN with several network printers and about 25 stations. I was told by a network engineer from an outside consulting group that our domain was setup incorrectly. Rather than having something such as "local" at the end of the domein name, for example "domain.local". I have even read that I should go one step further and make the domain something such as "internal.domain.local".

We have been assigned dns numbers from our ISP to get connected through our server, firewall, and IAD unit, and ultimately to the web. Our internal domain is not a published one nor is it intentionally visible to all on the web.

My dilemma is this... I can't find anything that enables me to change that domain name. I need to know what it takes to change that name, as well as update the workstation pc's to recognize the change.

Any suggestions or tips would be greatly appreciated.

rename domain

by afram In reply to domain changing

I don't think it's worth the trouble of changing domain names. You certainly don't need to change it just because it doesn't start with internal or end in local.

Did they provide a reason why it was set up incorrectly other than the name?

I know that many people who set up domains seem to want to do it "their way" and anyone else's way is wrong.

to everyone:
I also don't think you can just change the name...would it be correct to say that you have to

create a new forest, (or introduce a new server with a new domain) create a trust, create the users on the new forest, set the permissions, then have the workstations join the new domain?

domain name

The other way od doing this if the use of snother server is unavailable si to demote your server and then promote it as an AD server again which I might add is a huge pain in the @$$.

I thought as much

by callupchuck In reply to rename domain

That's kind of what I was thinking also. The consultants did say that the zone would need to be deleted and re-built. All I know is that their recommendations state that: Clean up network services and TCP/IP by reconfiguring DNS and DHCP. But they never stated what that means and if it is possible for me to accomplish the task at hand .

.LOCAL domain name

by BFilmFan In reply to domain changing

Provided that your internal DNS namespace will never be published on the internet, you shouldn't have an issue.

However, if should someone register your DNS name space with the Internet, then you will have issues. The question is what are the chances that your name will become published on the Internet?

Most engineers do recommending appending the DNS namespace with the .local extension to prevent issues.

What OS are you using?

I see, I think...

by callupchuck In reply to .LOCAL domain name

We are using Server2000 and a name that is similar already to URL's already in use on the internet. I guess I am confused as to how our local domain could interfere with a url on the outside, if we are behind a firewall and are not utilizing any outside services such as an ftp server or the like.

How DNSWorks

by BFilmFan In reply to I see, I think...

I am assuming that you do have clients which browse the Internet?

How would your internal DNS know which named server would resolve to which address if names are duplicated on both the local network and on a public published network ie The Internet?

You simply cannot have 2 different servers claiming to have Start of Authority records for mycompany.com domain.

I would recommend that you review the information contained in the Web Sites below for a better understanding of DNS:
