I have Outlook Web Access that won't resolve on our Windows domain DNS server.

For example, on the URL if I type:

https://mail.mywebsite.org/owa

Then it does not work.

However, if I use the dns address

https://10.15.83.2/owa

Then it works.  What do I add to the dns forward lookup table to fix this issue?

All you should need to do is create a Host A record for your mail server. It iwll be in the form of

mail.mywebsite.org and an ip address of 10.15.83.2

Something must be wrong, because I do have an A record for that.

I notice also on the PC's that the DNS Server under ipconfig shows

2001:558:feed::1
2001:558:feed::2
10.15.83.10

The last one is my DNS server.  I have no idea why the computers are showing the first two.  What is that all about?  Could that be the problem?

The first two that you are seeing look like IPv6 addresses.

So a few more questions for you. Is your primary domain name the same as the address you are trying to use for the mail? IE your domain name is mywebsite.org and your owa site is the same domain?

Also on your client have you ran ipconfig /flushdns

So if you look in the dns console you can see the entry for mail.mywebsite.org listed as an A record with the correct IP address? Can you take a screenshot and post it (blanking out any sensitive information).

Also how many DNS servers do you have in your environment is it possible you are waiting on replication to occur to your other DNS servers?

Actually nevermind I know what the issue is. It took a little bit of googling but you have Comcast DNS servers set before your internal DNS server.

"If you have manually configured your DNS IP addresses, we recommend you switch back to receiving them via DHCP and then release/renew your DHCP lease. If for some reason you wish to manually configure your DNS servers, you may use the IPv4 addresses 75.75.75.75 and 75.75.76.76, and IPv6 addresses 2001:558:FEED::1 and 2001:558:FEED::2. - See more at: http://dns.comcast.net/index.php/help#sthash.p8faAZqW.dpuf"

If you are setting your DNS by DHCP you will want to put your internal DNS server first. If you were to manually specify your DNS entries you could add yours first and it will work.

So maybe I could specify my server first on the Comcast router.

Are you are getting DHCP from your router that could work for you. I would try statically setting it on your machine first to make sure you can resolve using the name.
