Adding an internal DNS record for our mail server

We already have a DNS record on our server 2003 box for an internal route from our external IP address to our mail server for webmail access. This does not work internally.

I need to create a DNS pointer to point to our mail server's name for internal access from webmail.ourdomain address so users can access it... as if it were in their hosts file.

How can I do this? I've tried creating another record but It will only conflict with the existing one for external access.

You need to create a forward lookup zone, see my guide here on how to do it: http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/A_3703-Use-iPhone-on-wifi-network-without-the-need-to-reconfigure.html

The guide is intended for smartphones etc, but the process is identical for what you need.

I saw that guide... I've done as it says and currently receiving "ping request could not find host"...

Tried the usual flush/registerdns. Hopefully tinkering with the DNS creating a new forward lookup zone won't stop other hosts on the network being accessed.

so you have created a new forward lookup zone and a blank A record within that zone?

If you run IPCONFIG /ALL on the client, is it using only internal DNS servers for DNS names resolution?

Yep. The one I'm creating the lookup on is primary

and if you run NSLOOKUP and then enter the owa.domainname.com record what do you get back?

tegeniusAuthor Commented:
It's bringing back the entry in our domain.local zone, because one exists there to route traffic from our external IP to owa.

Oh.... I think it's working. Might have just taken a while to propogate. I'll test external.
