External website access from network

I have inherited a network where the DC is configured as domain.com and not domain.local (which is how I do it). The users have never been able to access their own website internally which is the same domain name the DC domain

Since I have never done this how do I configure the DNS on the DC to allow for access the to their website?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

One way is to have your DNS on the DC resolve www.domain.com to the IP address of the web server.

Make a manual entry for www.domain.com and resolve to IP address
Gerhardpet wants to acces the webpage as domain.com, and not as www.domain.com. This can be possible only if the DC has also the role of webserver (IIS enabled) and there the webpage must be installed. It can works if you have a single DC. You can also redirect from IIS the domain.com to another site, but it can be tricky. But if you have more than one DC .... I realy don't know!

Another option is to migrate your AD domain.com to int.domain.com

Both options are tricky and need strong knowledges. I never did it! :).

I think that everyone should learn as a best practice, recomanded by Microsoft, when an AD is implemented, it should be set as a subdomain of  the company's domain name, for example int.domain.com.

Gerhardpet you inherited this, so that's life, but if you want to change that, there is no other ways.

Good luck!

What I attempted to do is buy a new domain as domain.co and then forward that to domain.com with masking.

That does not work either. It should I think because then internally they access the site by domain.co.

I can access domain.co and it does mask when access the website

is there something I could set on the DC for the masking to work internally?
No, there is not such thing. The only solutions that you have is what I have presented to you earlier.
Where is your web server? In your DMZ, or at an ISP outside of the company? And, so that we are all clear: are you trying to access the web site via domain.com or www.domain.com? This needs to be clear.

I would NOT run a web server on the DC.

The web is hosted at an external ISP and it an oscommerce site so hosting on Windows is not an option. The external website is configured as www.domain.com
What you had described is a common mistake when people design an AD site. Try adding a manual entry in your DNS for www.domain.com resolving to the ISPs IP address allocated for your web site.

You were correct. It does work after I created a DNS entry for www pointing to the external IP address.

The website is configured as www.domain.com so I'm good to go.
