  • New Exchange 2003 FES, OWA Http error 404

    Hi Guys,

    I posted a question recently about implementing a new FES in our organisation. Having done so i've got a problem. Our set up is currently as follows:

    1 x Back end server running Windows Server 2003 Enterprise, Exchange Server 2003 SP2 with all hotfixes.
    1 x Front end server running the same.

    The back end server hosts all the mailboxes and the FES is used to provide OWA access for clients internally and externally. The existing FES was originally setup by a contractor but is proving not to be powerful enough so we want to implement a new one on more powerful hardware.

    When the FES was first installed it was built with HTTP virtual servers. The original was left in tact and a new one was made for clients to access OWA. The only configuration difference on the new one was that it was given a different hostname.

    I've built a new exchange server and added it to the organisation. I've marked it as a front end server and using the default website i can access user mailboxes without a problem. However, when i create the second HTTP virtual server and give it a seperate hostname i have problems accessing my OWA.

    When i specify the site name i get the log in prompt but after entering my username and password i'm faced with an "HTTP Error 404 - File or directory not found" page. If i specify the site /mymailboxname i get prompted for my password then given an "HTTP/1.1 503 Service Unavailable" error message. Does anyone know where i should best start my troubleshooting efforts?

    - I'm assuming the FES contacts the back-end ok as the default website works.
    - All settings on the new site are left at default (as they are on the default website)

    Any suggestions?

    regards

    What is your reason for wanting to use another virtual server? It isn't something I tend to recommend with OWA.

    How did you create the second virtual server?

      The only reason being that when the original FES was setup, it was done by a contractor who added a second Virtual server so that we wouldn't have to type /exchange into the URL.

      I'm aware that there are other ways of getting rid of the need to type /exchange but i just thought i'd keep the new server the same as the existing one.

      I created the new server via exchange system manager. The only configuration settings i did was to add a new hostname under the advanced tab. Other than that, all settings are at their default which is exactly how our existing FES which DOES work is configured too.

      I'm completely stuck for ideas now though as i've run through about every article i can find on peoples websites, forums and the knowledgebase regarding 404 errors.

        The contractor's method was flawed. The fact that it was done by an external party doesn't mean that it was done correctly. There is no reason to try and maintain a flawed deployment.

        What I would do is remove Exchange using add/remove programs, remove IIS. Reboot the machine. Reinstall IIS and Exchange and the service pack.
        Enable the frontend server option and then test the server. If it works correctly, make the simple change to remove the /exchange requirement in IIS.

        I have a screenshot of the change to IIS configuration on my web site:

          Thanks for your reply i've now got it working using the /exchange switch in IIS. I made an insteresting discovery before i got it working this way though. I upgraded v1.1 of the .NET framework to v2. After doing this i deleted and re-created the second website and got the following error message in the event log:

          Event Type: Warning
          Event Source: ASP.NET 2.0.50727.0
          Event Category: Setup
          Event ID: 1064
          Date: 20/10/2006
          Time: 14:40:58
          User: N/A
          Computer: PGSMAIL2
          Description:
          Failed while creating files and directories in \\.\BackOfficeStorage\pgs.org.uk\MBX\aspnet_client . Error code: 80070003

          For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

          Does anyone have any idea what would cause this? I don't know a great deal about IIS or ASP.NET myself but what would be causing this? I guess some kind of permissions issue but don't know what directories it's trying to write to etc.

            ASP.net v1.1 and 2.0 are not compatible with each other. They are effectively two different applications. Therefore you can have 1.1 and 2.0 running on the same machine. OWA is not asp.net 2.0 compatible, so if you tried to change the asp.net version that it was using, that would break OWA.
