OWA "Internet Explorer cannot display the webpage"
Details details, here we go.
I have a Web Server with two nics. 10.1.1.x for interal access, and 10.2.2.5 with a direct DMZ to the www. The website works fine on both nics. OWA works fine on the 10.1.1.x nic (or connecting from the inside.)
The firewall has one access rule for the DMZ, that's ALL traffic to DMZ both ways.
The server has two webservers(services) running. WAMP and IIS. WAMP for the website and IIS6 for OWA.
Things I've tried. (the not so obvious)
1: I've created a new website in IIS using the same SLL cert directing to a folder named exchange with a file named text.txt inside. When connecting to it from outside, it prompted for user/pass, then directed me to the text.txt file. Works fine. Confirms that the firewall is wide open and ssl ports work fine.
2: I disabled the 10.1.1.x nic on the webserver to force this test, to make sure there is no issue with 10.2.2.x and 10.1.1.x for some reason.
1: Could there be some DNS HOST, A, MAIL or something added for this? But it works internally, just not external. And our normal mail works just fine. Just a thought, but not sure where to look.
I've been wrestling with this for a few days, any thoughts?
