DNS resolution problem

I have installed a windows 2008 R2  server. The local domain name is LGBS-SRV1.LGBS.local.

The site has a website elsewhere www.lgbs-law.com

There is an on site conference bridge that has an IP of 192.168.1.33. This conference bridge is accessed using a url of conference.lgbs.com. The server is at 192.168.1.10.

Prior to putting in the server the local PC's accessed the bridge by opening a browser and going to http://conference.lgb-law.com. To accommodate this, I put an entry in the hosts table of each computer to route that URL to the local IP and it worked fine.

Over time as computers got replaced and windows 7 machines started to move in, I had forgotten to add the entry to the hosts file of each individual PC.

I would like to get this back on track and prevent future problems. Is there a way to get the DNS server in the windows server to resolve that address to the local IP?

I still need the lgb-law.com to resolve to the website, however I need conference.lgb-law.com to resolve to the local IP.

Thank You in advance.

Create a forward lookup zone for lgb-law.com.

Add a static record for conference with your IP address.

So if any of your DNS resolvers tries to access conference.lgb-law.com, it will query your local DNS server first.

Is your internal DNS name .lgb-law.com?

You could create a DNS zone called conference.lgb-law.com create a A record to that IP address

I will test this in the AM, but, it sounds like just what I want, In the event that I missed something.

My internal DNS name is LGBS.local.

The firm website is LGB-LAW.com and is externally hosted.

The users still need to go to HTTP://WWW.LGBS-LAW.COM, however, The conference bridge is internal to the site and has an IP of 192.168.1.33 and is accesses with the URL http://conference.lgb-law.com.

Thank you all for your help so far.

The main problem given the public domain exists, if it is not your and they have a conference.lgb-law.com, your internal users will not be able to access it.
Dariusg's suggest to use the conference.lgb-law.com as the zone you add will limit the impact..

The internal Dsn authoritative zone is better than the hosts option.
You could as part of a GPO startup script for computer configuration, push a host file to each member system in the domain, or OU as needed.  Once setup it will copy the file on every boot.

OK - I am testing now.

When I create the forward lookup zone for LGB-LAW.com, do I also need to add an A record for the website (www.lgb-law.com)?

Apparently, I need to create a reverse lookup zone as well. I am researching that as I write this.

Thank you all for your help so far.

Not if you use the example dariusg's suggest and create the forward zone as conference.lgb-law.com and then create the host record as
@ in a 192.168.1.10
And that should do it. You internals system will query the internal Dns.
