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.
