Question

Autodiscovery SRV DNS record in Exchange 2007

Asked by: aiscom

I am trying to resolve a couple autodiscovery and OAB issues I am having with Exchange 2007.  I found this link which talks about creating a SRV record for autodiscovery:
http://support.microsoft.com/kb/940881

My question is, we have a domain at the office which is the same as our external domain (mydomain.com).  I have created this record on our internal DNS server with no effect.  Do I need to have this record created externally?

Thanks!

It depends where you wish to use it. If it's for external use then you must also add it to the external DNS server (if they support SRV Records).

If it's internally, exactly what have you added? It should resolve if you do:

nslookup
set type=srv
_autodiscover._tcp.mydomain.com

Under the Forward Lookup Zone in the DNS Console you should see mydomain.com, then _tcp (looks like a folder), then the _autodiscover record.

Internally it shouldn't matter unless you have clients who aren't on the domain. Outlook should pull the information that it needs from the Active Directory.

I will check with my ISP on if they support SRV records.  We plan to use Outlook Anywhere both internally for a couple clients, as well as externally.

I did create the SRV record in my forward lookup zone (mydomain.com).
Service: _autodiscover
Protocol: TCP
Port Number: 443
Host offering this service: mail.mydomain.com

When I run nslookup on my internal DNS server though  it says it cant find autodiscover._tcp.mydomain.com.  I noticed there is an A record also in my forward lookup zone (cant remember if I created it myself or not) that points to the IP address of our Exchange 2007 server.
