Server Application Unavailable!! - ASP.NET General

This morning I was quite happily working away when a Windows Update prompted me for install. I found a convenient brake point and duly installed it and rebooted, oh dear what a mistake LOL! Any asp.net page now fails with the following message: - Server Application Unavailable The web application you are attempting to access on this web server is currently unavailable.

    Default Server Application Unavailable!!

    This morning I was quite happily working away when a
    Windows Update prompted me for install. I found a
    convenient brake point and duly installed it and
    rebooted, oh dear what a mistake LOL!

    Any asp.net page now fails with the following message: -

    Server Application Unavailable
    The web application you are attempting to access on this
    web server is currently unavailable. Please hit
    the "Refresh" button in your web browser to retry your
    request.

    Administrator Note: An error message detailing the cause
    of this specific request failure can be found in the
    system event log of the web server. Please review this
    log entry to discover what caused this error to occur.

    Now I have looked at the millions of posts to do with
    this and firstly I get nothing in the event log, so I
    have no idea whats caused it??

    The 2 Windows updates were: -

    An IE6 security patch
    A Data Access Components security patch

    Am I the only person this has affected??
    Anyone any ideas as to a solution??

    Thanks in advance

    Hi Andy,

    I was also facing same problem with my .NET Web Apps. I changed userName
    attribute to SYSTEM in the <processModel> section of the Machine.config file
    on my machine.

    It worked for me. Hope works for u also....

    Cheers

    Hi

    Yes I'll try that although I'm doing a System Restore at
    the moment out of desperation!

    SOLUTION (for now):

    PROBLEM: The ASP.NET process runs under the "ASPNET"
    local user account. After installing the updates, it is
    required that the ASP.NET process have read access to the
    folder:
    \Doents And Settings\LocalService\Local
    Settings\Temporary Internet Files

    I don't know why it needs those rights, or if it will in
    the future, but for now, here's the fix.

    SOLUTION:
    1. Yes, you can have the ASP.NET process run as SYSTEM,
    but this is a SERIOUS security issue.
    2. Better, and simpler, is to give the ASPNET account the
    permissions it requires. Below I will outline how to
    implement this.

    FIX:
    1. Open Windows Explorer, navigate to
    \Doents and Settings
    2. If the "LocalService" directory is NOT visible, you
    need to choose "Folder Options" from the "Tools" menu.
    Then you need to ensure that under the "View" tab,
    protected OS files are NOT hidden!
    3. Continue on to
    \Doents and Settings\LocalService
    4. Right-click on the "Local Settings" folder, then
    select "Sharing and Security".
    5. In the "Security" tab, "Add" the "ASPNET" user, and
    make sure it has "Read" and "List Folder Contents"
    permissions.
    6. "Apply", "OK", .... etc until all windows closed.
    7. That's it.

    Hi Andy,

    The Server Application Unavailable issue you are seeing right now is related
    to an issue with the latest IE security patch on Windows XP Pro and IIS 5.1
    when using ASP.NET v1.0.

    This page below has a description of the problem, as well as a workaround
    you can
    apply immediately:
