Empty treeview

edited October 2004 in Server
At one of our customers we get an unexpected result. The explorer frameset
opens, but both frames (Including the treeview frame) are empty. When
looking in the source code, there is nothing between the tags
in the treeview.

We are using the ISAPI-tier.

Does anyone have any suggestion what might be wrong, or how this can be
resolved?

    Do you get a page not found error? or just empy pages.

    An empty page would indicate that no report volumes are registered with the
    server. Check the report server application.

    An empty explorer with two page not found errors indicates a configuration
    issue. Check the webtier properties and the IIS and security accounts.


    ----------------------------------------
    RB WebTier and IIS User Accounts
    ----------------------------------------

    Question: I am trying to configure and test the RB WebTier using IIS. When
    I try to test the web tier via my web browser an Internal Server 500 Error
    page is displayed.

    This is generic error page returned by IIS.

    One cause of this error is that the WebTier application does not have
    sufficient user access rights.


    Solution:

    1. Unload the WebTier application.

    Use IIS to access the properties dialog for the rbWebPub virtual directory.
    Press the UnLoad button to unload the ISAPI dll.

    2. Delete rbWebPub subdirectories

    Use Windows Explorer to delete all subdirectories inside the rbWebPub
    directory. If you are using different WebTier CacheDirectory or WebTier
    LogSettings, then delete those directories also.


    3. Configure IIS User Accounts

    There are two user accounts created by IIS: IUSR_MachineName and
    IWAM_MachineName. (MachineName is replaced by the name of your computer).

    a. Use Windows Explorer to access the properties dialog for the rbWebPub
    directory.

    b. Check whether the IUSR_MachineName and IWAM_MachineName accounts appear
    in the list of users. If not then add them.

    c. The IUSR_MachineName account is the Internet Guest Account. This account
    requires Read, Execute, and Write access to rbWebPub.

    d. The IWAM_MachineName account is a user account that IIS uses to run web
    applications such as the web tier. This account requires full control of the
    rbWebPub directory. The web tier must be able to read, write, and create new
    files and sub directories for the CacheDirectory and the Log. Therefore if
    you configure the WebTier to use directories that are not subdirectories of
    rbWebPub, you will need to configure those directories as well.

    e. reboot the machine.

    This is a tough one for me to diagnose. There has to be a difference between
    what is running at the other customer sites and what is running at this
    particular site.

    We have had no other reports from customers of any issues like this.

    As a test, try creating a simple client application that asks the server for
    the report catalog information. For an example, check out
    RBuilder\Demos\Clients\ReportCatalog\ and the online help topics for
    TrsClientReportCatalog.

    Do you have a server deployment license for each server installation?
