IIS and Web mail...

Reply Contact

Hello all,

I am having trouble with Outlook Web Access and our 2 domains. I believe it to be an IIS 6.0 issue, rather than Exchange though. Here is what is happening.

An employee, when accessing email from outside the network, types in "http://mail.domain.org"

We have a redirect script in place that is supposed to take the employee to "https://mail.domain.gov/exchange" but never does. The employee gets sent to the .org domain.

Security cert. is issued to the .gov domain. DNS is pointing to the correct domains.

I have tried various combos of host headers, and IP addresses.

I believe that the issue lies with the certificate. If I create a test web site (one that points to .gov) that does not require SSL, it takes me to the correct place. Once I require SSL, it takes me to the .org site.

Forgive me if this makes no sense or if it is a simple problem, but this is my first foray into IIS.

What are the details of this script?

Hi Tom, here is the exact script....

<html>

<head>

</head>

<body>

<p>You are being redirected to the secure webmail site. If you aren't redirected, click the link below. </p>

<p><a

href="https://mail.domain.gov/exchange">https://mail.domain.gov/exchange</a>

</p>

</body>

</html>

Our initial OWA site is mail.domain.org/exchange

Thanks,

Craig

Get Fiddler2 from http://www.fiddler2.com/fiddler2/ and trace the HTTP calls to make sure you are going where you think you are.

What happens if you click the link instead of waiting? Are there any redirects set in IIS? What if you just used an IIS redirect?

Hi Tom,

Clicking on the link before it redirects by itself brings me to the same place. To the .org domain. Within the redirect script, I substituted "www.msn.com" for "https://mail.domain.gov/exchange" and I get brought to msn.com. This leads me to believe that the redirect script is OK. Is there some rule that if 2 sites on the same server both require SSL, then the traffic will be routed to the site with a Certificate applied to it? Or maybe something along those lines?

Are both sites assigned their own IP addresses?

Did you disable socket pooling?

When this issue was handed to me (it was dropped in my lap-probably a common occurance for all of us here), there was only the Default web site set up. The IP address was set to "All Unassigned" I have since changed this to a static IP address, and I copied this website and created another website with a different IP address. It still does not work. We want the content of these websites (in this case, they are for web email) to be identical. Once we can get to the correct domain (.gov), we will deactivate the original domain (.org).

I have an idea and please tell me where it is flawed... If I stop the first web site (the domain.org site) and remove the certificate, and apply the cert. to the new (the domain.gov site) website, then OWA users will be pointed at the correct location. However, I cannot do this during working hours for obvious reasons.

Socket pooling has not been disabled. I was under the impression that as long as these sites have unique IP addresses, then they can both use port 80 without a problem.
