Hi

Iam Transitioning my exchange 2003 to 2010 andi have  decide to give users OWA from the external  world and internal to our network as well. I created a external DNS on our name server  as:   mail.gokul.co.uk to point to our external  IP and nating on our Firewall to point  to our Internal exchange IP. Now it resolves the name from out side when i ping mail.gokul.co.uk

But how do i configure within my network  so that  mail.gokul.co.uk points to  exchange 2010
internal IP to my network.My ideas is when a user types https://mail.gokul.co.uk  within our network. It should bring OWA login page. Any tutorials and sugession appreciated

Thanks

I presume your AD is not called gokul.co.uk?  If so, what you can do is to create a new zone on your AD DNS server called gokul.co.uk and then create a CNAME in that zone to point at your mail server, which I can imagine would be gokul.local.  You now have to be very carefull because since you have an authoritatize DNS zone server for that domain (gokul.co.uk) inside your network, any other hosts such as www.gokul.co.uk will not resolve to an IP.  However all is not lost since you can create a new A record in the gokul.co.uk zone on your AD DNS server) and point that A record at the IP address of the WWW server.

From a design and operations perspective you have to remember that DNS is a "subjective" service.  It always answers from it's own point of view.  In most cases it also knows where to get answers if it cannot answer queries by querying other defined DNS Servers (forwarders).

If it however is authoritative for a zone, it will not ask other servers for an answer and will ALWAYS answer the query, even if it does not have the answer.

Scenario 1, your domain is NOT gokul.co.uk (covered by wynandkunkel): Please do as suggested
Scenerio 2, your domain is gokul.co.uk: Add a CName mail.gokul.co.uk to your existing forward lookup zone

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

My AD domain is called:  cleeve.local
and my domain is:  cleeve.co.uk

So If a user types https://mail.cleeve.co.uk  within our network. It should bring OWA login page.

Any tutorials as how to create a new zone on my AD DNS server and then  create a CNAME in that zone to point at my mail server will be vey helpful.

Thanks

1. New Forward Zone

On your AD server go to DNS and right click on the server.  Select New zone, then select Primary zone and Store the Zone in AD, then select to all DNS servers, the select Forward lookup zone and type in the name of the zone "cleeve.co.uk", and then select only allow secure updates, and Finish

2. New CNAME

Expand the zones and right click on the cleeve.co.uk zone,  select new Alias (CNAME), type mail (you will see that in the next text block the FQDN will appear), and then browse for your existing mail server, Then OK

That's it, done!

dont forget to Add any A pointers to your cleeve.co.uk if you have a domain by that name running on the internet.
