OWA DNS Issue on SBS 2008 Server

We encounter a strange behavior, OWA webpage can't be reached (https://remote.domain.com/owa or https://servername.domain.local/owa) from the server itself (with IE or Comodo Dragon) while it is working from any other client computer or server of the domain.

It works with https://127.0.0.1/owa but not with the IP of the server (https://10.0.0.2/owa)...

The DNS Host A record is present in the DNS server...

Any idea ?


Thank you in advance for your help !

try pinging the addresses below and assess if the correct IP is returned.

Does the server have multiple NICs?

https://remote.domain.com/owa
https://servername.domain.local/owa


I've actually seen something odd like this once before. It was following the removal of a rather nasty virus. Don't suppose you've had any issues recently have you?

Try having a look at netstat -anbo > C:result.txt to see what is listening to port 443 on 10.0.0.2 (just open c:result.txt in notepad)
If any processes other than IIS stuff is listening to that port you may have something dodgy installed. (viruses rarely seem to take over 127.0.0.1 for some reason)

Hello,

Presuming that the DNS on the server is set to itself?

What version of IE are you using?

Do you get the IIS landing page or an error?

What happens if you try https://servername/owa (no domain)?

Check the site bindings in IIS on your exchange server.
You may have to add 10.0.0.2 and https://servername.domain.local/owa in there.

I posted and the post disappeared...

I found that it works fine on IE now, it couldn't work on Comodo because of the Comodo secure DNS installed for the navigator...

Thank you anyway for your help !
