  • If you close open files or resources, users might lose data. You may want to warn connected users before you close an open file or resource. For more information, see Related Topics.


  • You must be logged on as a member of the Administrators group, Server Operators group, or Power Users group to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.

  • You can use Shared Folders to manage shared resources on both local and remote computers. For information about how to connect to another computer, see Related Topics. With Windows Explorer and the command line, you can manage shared resources on your local computer only.

  • When you administer another computer remotely, your connection appears as an open named pipe. It cannot be closed.

  • File sharing options may be limited if simple file sharing is enabled. For more information about simple file sharing, see article Q304040, "Description of File Sharing and Permissions in Windows XP," in the Microsoft Knowledge Base.

Information about functional differences

  • Your server might function differently based on the version and edition of the operating system that is installed, your account permissions, and your menu settings. For more information, see Viewing Help on the Web.
