Help with restore of User Data Folders and Exchange Mailboxs

    I would like your advice on how to recover from a server failure. Short
    story is that I had to reformat drives and reinstall SBS. The SBS is now
    installed (using disks 1-5 of the R2 release, I didn't apply R2
    technologies) and is at SP2 with all subsequent updates.

    AD was lost so I have now recreated Users and Computers using the Wizards
    and am now running /connectcomputer. There are only 25 Users and Computers,
    all clients ar XP SP2.

    Before the crash, folder redirection (intelli-mirroring) was applied at
    logoff so all Users have a CSC. As well they have an .ost for Exchange.

    However, when they connect and the synch occurs their files are not being
    copied to the server. I suspect that is because the User "Nancy" has a
    different identifier in her CSC than the server now has in her Users Data
    Folders. How can I force the cached files on the XP to go to the server
    target folder?

    Same with the Exchange. How can I recover their .ost into their new mailbox?

    Thanks for your help.

    (by the way I do have tape backups that ran every night but the ruddy tape
    drive can't read them (PowerVault DLT110T VS80). I have ordered a new one
    from Dell (VS160) and can then get other files but in the meantime I should
    be able to get the Users back on their feet).

  2. Hi,

    Thanks for posting in our newsgroup.

    Based on current situation, you can recovery files in CSC first, then copy
    to the server.

    The offline files were stored in the folder %SystemRoot%\CSC. The contents
    of the CSC folder can be restored from a previous backup, however, if you
    don''t have such a backup, it's very difficult to recovery the cached data.

    To recover offline files, let us try the following steps:

    1. Open the %systemroot%\CSC folder.
    2. There will be numbered subfolders within CSC. Each subfolder will have
    one or more data files. These do not have any associated icon or file
    extension and use the following nomenclature: ########.
    3. Open the properties of the document and refer to the summary tab. The
    advanced view will need to be enabled.
    4. Look for the Origin subdirectory and then "Application Name." This will
    tell you the application used to create the file.
    5. Close the properties, right-click the file again, and this time use the
    "Open With ... " feature to select the correct application identified in
    the previous step.
    6. You should be able to open the file and save the cached copy of the file
    onto the local hard drive.

    Since we don''t have a data recovery tool for this scenario, you may also
    want to use some third-party tools such as Easyrecovery
    <http://www.ontrack.com/easyrecovery/>.

    To recover an ost file, authentication is required.

    If Exchange server is available, the authentication can be processed via
    the Exchange server. When we open Outlook with the ost file in connected
    mode, this authentication method is used. Also a corresponding token will
    be added into the registry with this Exchange account.

    If the Exchange server is available, the authentication can be processed
    via Outlook. Outlook compares the authentication info with the one that has
    been cached in the registry. If the user''s credential is correct, the ost
    file can be open.

    In this situation, I am afraid that we may not be able to open the ost file
    because the original Exchange server has been removed and the Exchange
    account was deleted too.

    I am not sure how he created the new Exchange server. But if the new server
    is not in the same org or same domain with the original one, I think the
    ost will not be open. If they rebuilt the server in the original domain, I
    am not sure if the ost file can be open and you may need to test this.

    The good new is that there are lots of third party recovery tools that you
    can use.
