SYMPTOMS

When a client plays back media content from a Microsoft Windows Media Services 9 Series server, the client typically sends a log file back to the server. This log file contains playback statistics. Some mobile clients send a log file that has a malformed date field. When the server receives a log that has a malformed date field, the server registers a 408 status code for that client connection instead of the expected 200 status code.

CAUSE

This issue occurs because the server discards the client log. The server does this because the data is malformed.

This hotfix also gives server administrators the ability to add other custom-defined operating system names and player versions to the registry. If a client that has a matching string sends a malformed date and time, the server will still correctly write the log file.

To add more user agent strings, follow these steps:
  1. Start Registry Editor.
  2. Locate and then click the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media\Server

  3. On the Edit menu, click Add Key, and then add the following registry value:

    Key name: ClientLogging

  4. Click the ClientLogging key.
  5. On the Edit menu, click Add Value, and then add the following registry value:

    Value name: DateTimeWorkaround
    Data type: REG_MULTI_SZ
    Value data: Each string represents the client version and the client operating system on which you should also apply this hotfix. The string uses the following format:

    Version;OperatingSystemName

    Note Version represents the major part of the version number, such as "10." or "9." OperatingSystemName represents the name of the client operating system, such as "SmartPhone".

  6. Exit Registry Editor.
