  • Need to fix OWA and figure out OMA

    Hello

    I am sure that many aspects of this question have been beaten to death - however I hope that I can get some guidance here. Bosses recently ditched the beloved Blackberry and went with Windows Mobile based handhelds. Now I need to get OMA working. In so doing, I have somehow broken OWA.

    I've removed and re-created the Exchange virtual directoris in IIS as per this:
    http://www.msexchange.org/tutorials/...tallation.html

    At one time OWA was working - but I had noticed some problems at times accessing it internally. However, prior to me messing in IIS today, it was working.

    Now when I try to browse to https://servername.domain/exchange, IE tells me "Cannot display page".

    If I try to browse to https:/servername.domain/certsrv I get the same thing.

    Server is running Win Server 2003 and Exchange 2003. I am sure firewall not an issue as OWA was working great before I started. Any help would be appreciated, but if any mods feel this question is beating a dead horse than please kindly lock/delete it.

    Thanks.

    When it comes to resetting the virtual directories, I only follow these instructions: http://support.microsoft.com/default.aspx?kbid=883380

    Remove any SSL certificates on the site and then run iisreset.
    Ensure that you have also removed the require SSL option that might be on the web site.
    Finally check that the asp.net version is set to 1.1, not 2.0.

    Then see if OWA works correctly on http.
    If it does then add the SSL certificate back in again.

      Sorry for a dumb question - is simply deleting the certificate out of [ConsoleRoot\Certificates (Local Computer)] effectively removing the SSL certificate?

        No, you need to remove it using the wizard in the web site configuration.
        There is an option to remove the certificate.

        You don't need to remove the certificates from the Certificates MMC.

          Haven't even made it to SSL yet - using regular http right now for testing. I am having a problem with my anonymous account. Symptoms are when I log on, the OWA displays dead links and no graphics (just small blue boxes with text). Page says "Loading..." but never does.

          On the ExchWeb directory, I have Anonymous access checked - if I enable Integrated Access, it prompts me several times for my logon and password, then works beautifully. When I remove Integrated, and leave only Anonymous checked, it gives the above symptoms.

          I am convinced it's an error on the Anonymous account - I have read several articles about configuring it, and synchronizing the passwords with the Metabase using adsutil - I have done that several times with no reported errors, yet still I am having trouble with it. The only thing I'm not sure about one thing - I have read that I need to allow the Anonymous account to "log on locally" - I cannot find where to do that. In AD, the Anonymous accout is allowed to log on to every computer. What do I need to do?

            The fact that it does work with integrated authentication enabled on the /exchweb virtual directory does seem to point to an authentication error.

            I wouldn't worry about resetting the permissions that the anonymous account has. If you had changed other settings then you would know about it.
            I would concentrate on resetting the IIS Anonymous user account to begin with.

              Well that seems to be working now.

              Next question - how to set OWA to use Asp.net 1.1? I saw on the Default Website properties that Asp.net was version 2.0 - there is a drop down box and I changed it to 1.1. However, all of the Exchange folders still are using 2.0 and I can't change it in the properties page - how to do this?


              *Edit - Nevermind, I just reset all the Exchange vdirectories. Now OMA giving me errors..boo

                Well, I got OWA and OMA to work without SSL. I've installed a cert (self-signed), enabled SSL, and can now access OWA via https:.

                Problem - with Outlook (trying to utilize RPC via Http, it keeps prompting me for my password - any idea why?

                Also, if I browse from the client to https://server.domain/rpc/rpcproxy.dll it prompts me for a password - I think that's killing it...any helpers?

                *Edit - if I browse to https://server.domain/rpc it prompts for a password and no matter what I try for username it won't authenticate

                  The prompt for username and password and then failing is normal. That is the expected behaviour. Repeated authentication prompt in Outlook is usually caused by an authentication mismatch - so basic set on the Virtual Directory, but NTLM set in Outlook, or vice versa.
