  • OWA Document sharing (file server)

    hello,

    I'm trying to get the document sharing feature to work.

    So far I've manages to open shares on the exchange server and a network hard drive (Western Digital MyBookWorld).

    When I try to access my file server I get an error message (see bottom of this post).

    I've tried adding the file server to the allowed server list, which I also had to do with the network drive.
    I've also tried enabling the guest account.
    And I've tried searching a lot on the internet but I just can't find anything about this problem.

    I really hope someone can help me with this, I guess it's a stupid simple permission problem, but I have no idea of where to find it.

    thx,
    Kiekeboe100

      Re: OWA Document sharing (file server)

      thx for your answer, but I have already tried that.

      I think everything is set up ok on the exchange server as I can access the exchange server and the network drive without any problems.

      I can't access my file server (or isa server, exchange edge server) which are in the same domain. I also have another file server not in the domain which I also can't access. The only option I haven't tried is a client pc (I only have one that hasn't been added to the domain yet which I can try, will do this tomorrow).

      thx anyway,

      edit:
      The title of the error window is "Authentication Failure". Which points me even more into the direction of security permissions I have to set up on the file server.

        The fact that you are getting a Sharepoint error makes me wonder if your are putting the address in wrong.

        When you enter the address, are you putting in \\server\share ?
        Have you enter the file servers in the format of server and server.domain.local in the file server field?

        I have just tested my own site and all I did was enable the feature both public and private access and then add the file servers. I had access without any other changes. Certainly did not have to enable the Guest account.

          well, I've added my domain to the internal domain list,
          then added server and server.domain.local to the allowed list.
          In both Public and Private Computer File Access the Windows File Shares and Windows SharePoint Services are enabled. (going to try to disable the sharepoint services)

          And no mather what I type in the url i keep getting that sharepoint error.
          I tried:
          \\server
          \\server.domain.local
          \\server\share
          \\server.domain.local\share

          when i try with the exchange server or the network disk it works perfect with just \\server-exchange.

          edit: disabling the sharepoint services doesn't change anything to the error message. Maybe this is just a standard authentication failure message where they forgot to mention about file servers.

            A concern I have is that you may have pulled around with the settings on the server and the virtual directories so much that are you are seeing authentication errors, because it isn't using the authentication settings you are expecting it to.


            At this time I would be considering setting up a second set of directories on another internal IP address and setting up the option from scratch. After adding a second IP address to the server, create a second web site that is bound to that IP address. Then use Powershell to create new OWA virtual directories.

            Also ensure that you have file access enabled as well as sharepoint and it is enabled for both public and private OR you are sure that you are accessing it the correct version. If you aren't using FBA then enable it so that you can be sure you are accessing the site as a Public or Private computer.

              Re: OWA Document sharing (file server)

              hello,

              i'm using an isa server with form authentication.

              on the exchange server I've only changed the authentication to standard authentication method, and selected integrated windows authentication and basic authentication.

              and in isa i've changed the virtual directories so I don't need to use https.

              Should I still try with everything set up standard?

              In both public and private access is allowed to file servers and sharepoint servers, also the web document viewing is enabled in both.

              Also keep in mind that opening the exchange server itself is working, as well as the network drive. Opening the clientpc also worked but I couldn't see any shared folders (but that's another problem, this also doesn't work in normal networking ). But I can't access the other servers (whether they are in the domain or not)

              thx for your help,
              Kiekeboe100

                Re: OWA Document sharing (file server)

                The ISA function is where I cannot help. I don't have access to an ISA site at present and I don't use ISA at home (I prefer to use a real firewall).
                The fact that the network drive works from the Exchange server is completely irrelevant to it failing to work through OWA. I suspect the problem is probably with ISA.
                If you use OWA locally internally and connect to http://exchangeserver/owa login as normal and then try to access the drive through OWA, does it work then? If it does, then the problem is with ISA.

                  hello,

                  I think you misunderstood me.
                  When I access owa it is always from my laptop, never from the exchange server itself.

                  I've now tried to connect to owa from my laptop on the internal network through the isa server as well as accessing the exchange server directly. Also tried externally through isa.
                  All these times i could get on owa with no problems.
                  When i then try to open a network share on the file server (or any server) this fails. When i try to open a shared folder on the exchange server this works. As well as accessing a share on a network drive.

                  To make sure it wasn't isa, I have tried again by logging in on owa on the exchange server instead of through isa, but this is also not working (except the exchange share and network drive)

                  thx,
                  Stijn

                    Re: OWA Document sharing (file server)

                    I am having the same issue:

                    I can connect to OWA with no problems, and I am using a "private" computer. I have specified both our exchange server EXCH1 and our file server FILE1 under the Allow List for Remote Files Servers.

                    Going through OWA Documents I can get to the shared folder \\EXCH1\Downloads, but I cannot get to any shares on \\FILE1 - I get the same error message

                    Does anyone have any suggestions as to where I can look for logged errors? There isn't anything in the event log for either EXCH1 or FILE1, nor anything in System32\logfiles that coresponds to the time of the attempts.

                    Thanks for any assistance,
                    -M

                      Hi,
                      I have the same problems.
                      I can access my share files which are on the same server as exchange 2007, but no luck with remote.... (to get clear, my exchange server has 2 interfaces. one is pointing to Internet, other to Internal LAN )

                      When I try to acess remote file server
                      I get: Outlook Web Access was unable to retrieve the requested SharePoint document or folder. This may have occurred because of the way your Microsoft Exchange and Microsoft SharePoint servers are configured. "

                      I have tried to put security permit ions for domain guest, everyone etc, but no luck.
                      I also have tried troubleshooting shares with filemon from sysinternals, and noticed that w3wp is connecting to my share folders which is on the same server as Exchange.
                      Used this tools on remote servers, but no luck at all....

                      I'm using Exchange 2007 SP1 with smartcard auth.

                        Dual homing an Exchange server is not recommended, so that is the first place I would look at as the source of the problem.

                        When entering server addresses you should enter both server and server.domain.local in my experience.

                        Simon.

                            I had a similar issue with OWA using Exchange 2007. This is how I was able to get the issue worked out:
                            Access Microsoft Exchange Console – Server Configuration – Client Access – Outlook Web Access – Properties – Authentication, I had to de-select “Use one or more standard authentication methods” and select “Use forms-based authentication method” and choose logon format domain\user name. Restarted IIS Admin and World Wide Web Publishing services afterwards.

                            Furthermore, when accessing OWA through the browser, the user has to choose “This is a private computer” on the forms-based authentication (FBA) page.

                            Here is a link to describe the OWA procedure for the user:

                              If forcing authentication to be basic ( or Forms based ) on OWA is enough to fix it then its probably a delegation problem. Basic credentials can be delegated without any further config.
                              With basic authentication you're actually giving the exchange server your password, it is then able to use that to connect to other servers.
                              However, with NTLM & Kerberos the server never gets your password, only the resoponse to a challenge which is useless for subsequent server's authentication requests.

                              This would also explain why you can connect to the exchange server's file-shares but no other machines', (as you're already authenticated to it.)

                              I'm using FBA/basic through ISA, but having ISA perform kerberos constrained delegation/authentication against the exchange server so my exchange servers never have my credentials to use for document sharing. To make it work I had to allow the exchange servers to delegate authentication to the fileserver (impersonate me) - this is done on the exchange server's AD account, grant it delegation on the CIFS service of your fileserver.
