  • Multiple domains

    Hi, I', new to these forums. So I hope the topic is placed in the right category.

    Btw. English isn't my native language, but I hopy you will understand

    The problem now is, I want to host another domain at my server.

    First of all;
    My primary domain works great, and I can send/recieve mail. But I had a big trouble to configure IIS for OWA.

    My OWA site should use a name called mail.domain.com, and the regulary website should respond to domain.com.
    I made a new virtual server for mail.domain.com, but its pretty diffucult from my point of view. At all times, IIS tell me that more than one site is started at this port. But several websites runs fine at port 80. I even removed my own website out of the default website, so that the default site respond to mail.domain.com.

    For example, when I enable SSL on the Exchange dir, it didn't work - The site only requires SSL, when I enable it on the Default Website, but then my AS and Push mail doesn't work..

    I know that SSL is the most secure way to connect handheld devices, and I will implement this later, when I find out how IIS works correctly.

    Well, the question for now is, how am I able to get mail.domain2.com to work probably?

    Thanks in advance
    Best regards,
    Carsten.

    Re: Multiple domains

    While using SSL is the most secure way of allowing handhelds to connect to the server, having the option "require SSL" enabled will stop the devices from working correctly.

    Do not confuse the option "require SSL" with your ability to use SSL. You can have SSL without that option enabled.

    What I do to ensure that users must use SSL is not allow http to work at all, so port 80 is not even open to the internet. The users may complain but they soon get used to it.

    If you want a second domain or host name to be able to access the server, then you just need to point the DNS entries for the second domain at the default web site. The only problem you will have is wanting to use two SSL certificates with OWA on different domains, which isn't possible on the same site.

    Exchange 2003 doesn't make it very easy to have multiple web sites, and if you have removed the default web site then you may well have damaged your Exchange installation. The default web site is not just used by OWA, but is also used as part of the day to day operation of Exchange.

    Recreating the default web site isn't easy. If you had left the default web site alone you could reset the folders following this article: http://support.microsoft.com/default.aspx?kbid=883380
    However I think you are looking at a reinstall of Exchange and IIS to get back the full functionality of Exchange. Due to the way that Exchange interacts with IIS, you have to remove Exchange before you can reinstall IIS.

    If that option isn't acceptable to you, then you will need to call Microsoft and pay their fee for assistance with getting the default web site recreated, as not having the default web site is not an option. Your Exchange server requires it for operation.

      Re: Multiple domains

      Thank you, for you answer

      My Default Website is as it should be, i just dont use it. ie. My OWA works even if i stop the default website.

      I copy'ed all the exchange dirs from the default website (Save configuration to a file), and imported them on another virtual site. It seems to work so far.

      The External DNS entries is made, and working.

      To point out the problem now:

      Mail.company1.com is leading to the OWA.
      www.company1.com is leading to a Virtual Site, holding company1's website.

      www.company2.com is leading to another Virtual site, holding company2's website.
      mail.company2.com should point to OWA for company2, this is where i stuck.

      Maybe the mail.company2.com should point to the same exchange dir as mail.company1.com - Then it's the user credentials that is figuring out whos mailbox to display?

      I did not really understand how to run multiple company via OWA.

      Again, thanks for your answer.
      Best regards,
      Carsten.

        Re: Multiple domains

        Exchange doesn't care what URL the user accesses the server on.
        Therefore if you have multiple domains then you could have a unique host name pointing at that server.

        The only place that you get problems is with SSL. That has to match the host name being used to access.

        If you have an SSL certificate in the name of mail.domain.com and a user accesses it using mail.domain2.com they will get an SSL error.

        Most of the sites working with multiple domains (hosted Exchange providers for example) will use a generic name. If you tried to setup a site for each domain it would get very expensive on SSL certificates and it really not necessary.

          Re: Multiple domains

          Thank you very much, Simon.

          If I understand you correctly; It's possible to let all users from domain1.com and domain2.com, logon via mail.domain.com.. Thats really what I need

          I have just a little question to this; Is it possible to logon to OWA, with [email protected], instead of domainx\name?
          Best regards,
          Carsten.

            You can login to OWA using the UPN if you wish.
            The UPN is different to the email address - although you can make the UPN the same as the email address if you are careful with account setup.

              Thank you again, Simon.

              I'll search around the forum, to find something about UPN.
              Best regards,

                After you add more UPN suffixes then you can go to the properties of a user under the Account tab and select the new suffix from the drop down list.

                Or if you want to script it http://www.microsoft.com/technet/scr...4/hey1206.mspx
