KB2541763

In certain situations, TLS/SSL handshake messages become too large to be contained in a single packet. In these situations, some third-party implementations of the TLS/SSL protocol fragment the messages before they are sent. However, the Microsoft implementation of the TLS/SSL protocol cannot parse fragmented messages. Therefore, Windows Internet Explorer on a computer that is running Windows XP, Windows Vista, or Windows Server 2008 cannot connect to servers that use a third-party TLS/SSL protocol. Additionally, you receive the following error message when you try to connect to such a server.

The page cannot be displayed.

Consider the following scenario:

  • You have a computer that is running a 32-bit version of Windows Server 2008 or of Windows Vista.
  • You enable the Windows Hardware Error Architecture (WHEA) feature.
  • You send a WHEA request to disable the processing of machine check errors.

In this scenario, the operating system incorrectly polls hardware for machine check errors.

Note: This issue does not occur on a computer that is running a 64-bit version of Windows Vista or of Windows Server 2008.

    • Windows 7
    • Windows Server 2008 R2
  • You install a virtual storport miniport driver on the computer.
  • You try to put your computer in hibernation, or the operating system tries to save a dump file.

In this scenario, the computer restarts unexpectedly, you receive the following Stop error, and no dump file is generated:

  • Windows Vista

KB2493869

Consider the following scenario:

  • You share files on a computer that is running Windows Server 2008 R2, Windows Server 2008, Windows 7 or Windows Vista acting as the file server.
  • You run an application to monitor changes of the shared files and folders on the computer from a SMB client computer by using the Server Message Block version 2 (SMBv2) protocol.
  • The application calls the FindFirstChangeNotification function and then immediately calls the FindCloseChangeNotification function to cancel the previous change notification.

In this scenario, the TCP session of the SMBv2 session is reset incorrectly after 4 minutes. Therefore, you may experience data loss or file corruption if you transfer data or files during the SMBv2 session.

  • You install an application that uses transactional logging on the computer, such as Microsoft SQL Server or Microsoft Exchange Server.
  • The log file of the application is saved on the root folder of a mount point.
