Clear system default sharing method uncover _windowsxp

Since the start of the Windows 2000 operating system, Microsoft has added a new network feature called Windows default sharing. Some friends will ask, why is it called "Default sharing"? Originally, there is an essential difference between these folders and our own manually created shared folders, where their share name will eventually have a "$" symbol, which is to hide themselves in the Network Neighborhood. This way, unless we know the shared names of these default shares in advance, it is not possible to go directly to those folders in the usual way. Initially this feature was designed by Microsoft to facilitate the day-to-day work of the system administrator, and by default they were turned on, but because of Windows vulnerabilities, these preset folder names have long been known, so These originally is the Microsoft kindness the function which has been set up in the use has become a huge security trap, the serious threat system and the server operation security, for this kind of "chicken ribs" function We naturally must "shut him not to discuss". Today, I have several of the most common way to clear Windows default sharing of methods listed, for everyone to refer to use.

　　 How to view the default share

The default share is hidden in the Network neighborhood, but it is a piece of cake for system administrators. The two methods that they use most often are the following

　　 method One: graphical interface mode

Double-click Open Control Panel, "Administrative Tools," to perform the Computer Management icon and expand Shared folders → Shares in the window shown in Figure 1, you can see all the shared folders for the current system in the right area (Figure 1 shows the most common three types of system default shares)

　　 method Two: command line mode

Advantages: Convenient and quick, the function is stronger than GUI way, suitable for senior administrator to use

Execute the command "net share" in the command Prompt window, as shown in Figure 2, when the system will display all shared folders on this computer (that is, hidden shares with $ characters)


【 Small Tips"As you can see from the diagram, the default Windows sharing can be broadly grouped into three categories: the first is" admin$ "sharing, which points to the current system working directory (Winnt directory). The second category is similar to the "C $, d$, e$ ..." share, which points to the root directory of each partition on the computer. The last category is "ipc$", which is what we often call "shared Named Pipes", and the famous null connection exploits the ipc$
