domain controller and website the same

I inadvertently created a local domain controller for a client using windows server 2012 R2 with the same name as her web domain.  Now, nobody can access the web page from the office.  I understand I can modify the host file on the workstations to get around this.  All the workstations (17) are Windows 7 Pro SP1.  What information do I need to do this.  Any step by step guide would really be appreciated.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The easiest solution would just be to add a static DNS record on your Domain Controller for the WWW record.

Create a new A Record in DNS that is for WWW and has the IP address of your externally hosted site.

This is not a big problem and in fact MS states that its a good practice to name the internal domain name  the same or similar to aid in integration. I agree with Neilsr that you simply need to add a record in your dns to point "WWW" to the correct external IP address. Of course if your websites IP address changes you will need to manually edit the www record. In your forward lookup zone simply add an "A" record type "www" and the IP and once you refresh your dns cache your internal devices will navigate to the website with no problems.
