Nowadays, every user is faced with the question of setting up a network in the Windows 7 operating system. If you are a home user, you will someday be faced with the task of setting up an Internet connection, synchronizing with a game Xbox console, and if you have several pieces of computer equipment at home, then in any case you will have to set up wired or wireless network, and one computer will have to distribute the Internet to all the others. In case you are working system administrator small office, you will need to set up a network with static or dynamic addresses. Unfortunately, many users usually try to set up a local network without having the skills to work with network technologies, and therefore carry out the settings at random, which causes them to have many problems during subsequent work. This series of articles is dedicated to various configuration methods local network, terminology, as well as connections to the World Wide Web.
Often, setting up a local network in operating systems Windows Vista,Windows 7, Windows Server 2008/2008 R2 begins with such an area for configuring network properties as the . With help this tool Network Configuration allows you to select network locations, view a network map, set up network discovery, file and printer sharing, and configure and view the status of your current network connections. In this article you will learn about managing this component.
Opening the Network and Sharing Center component
In order to use the functionality of the network configuration tool, you first need to open it. To open a window "Network Control Center and shared access» , Perform one of the following actions:
The following illustration shows the window "Network and Sharing Center":

Network location concept
Before you start working with this component, you should understand such a concept as network location. This setting is set for computers when they first connect to a network, and during the connection, firewall and security settings are automatically configured for the type of network to which you are connecting. Unlike the Windows Vista operating system, which uses the strictest network hosting firewall profile for all network connections, the Windows 7 operating system supports multiple active profiles, allowing you to more securely use multiple network adapters connected to different networks. There are four types of network location:
home network. This network location is intended for computer use in the home or on networks where users know each other very well. These computers can create and join home groups. For home networks, network discovery is automatically enabled.
Enterprise network. This network location is used in a small office hose (SOHO) network. This network location also has network discovery enabled, but you cannot create or join a computer to a homegroup.
Community Network. This network location is intended for using the computer in public places such as coffee shops or airports. This is the most restrictive placement and has homegroup join and network discovery disabled by default.
Domain network. If the computer is joined to a domain Active Directory, That existing network the network location type will be automatically assigned "Domain". A domain type of network location is similar to a work network, except that the domain configures Windows Firewall, Network Discovery, and network card determined by group policy.
The network locations available for user selection can be seen in the following illustration:

Network map
A network map is a graphical representation of the location of computers and devices that allows you to see all the devices on your local network, as well as how they are connected to each other. In the window "Network and Sharing Center" Only the local part of the network card is displayed, the layout of which depends on the existing network connections. The computer on which the map is being created is displayed in the upper left corner. Other computers on the subnet appear on the left. Infrastructure devices such as switches, hubs, and gateways to other networks appear on the right. You can see an example of a network map in the following illustration:
Rice. 3. Example of a network map
Two components are responsible for the operation of the network map in operating systems:
Link Layer Topology Discover Mapper (LLTD Mapper) - a component that requests devices on the network to include them in the map;
The LLTD (Link Layer Topology Discover Responder - LLTD Responder) responder is a component that is responsible for requests from the LLTD Mapper component.
By default, the network map can only be viewed for locations "Home network" or "Enterprise network". When trying to view the network map for locations "Domain network" or "Public Network" you will see the following message:

- Open the snap "Group Policy Management";
- Select a GPO (for example, Default Domain Policy, scope - entire domain) that will apply to a computer located on the domain network, click on it right click mouse and select the command from the context menu "Change";
- In the snap "Control Editor" group policies» unfold the knot Computer Configuration/Policies/Administrative Templates/Network/Link Layer Discovery and select a policy "Enables the I/O mapping driver (LLTDIO)";
- In the properties of the policy setting, set the radio button to the option "Turn on" and check the box "Allow operation for domain";
- Repeat the same steps for the policy setting "Enable Responder Driver (RSPNDR)";
- Update policy settings on the client machine using the command gpupdate /force /boot;
- Update your network map. The result is shown in the following illustration:
Network connections
After installing the driver for each network adapter, the Windows operating system attempts to automatically configure network connections on local computer. All available network connections are displayed in the window "Network connections". A network connection is a set of data required to connect a computer to the Internet, local network, or any other computer.
Open window "Network connections" you can in any of the following ways:

Conclusion
This article briefly introduces the components of the Network Properties Configurator for Windows operating systems - "Network and Sharing Center". The concepts of network location and network cards are considered, with the help of which the local part of the network card is displayed, the layout of which depends on the existing network connections. You've also seen the Network Connections window, which allows you to configure network connections on your local computer. In the next article, you will learn how you can configure clients, services, and network connection protocols using a graphical user interface.
We continue to look at the new and improved features of the new Windows 7 operating system. Next in line are tools for working with the network. In addition to them, in this article we will focus on new troubleshooting tools, features of the updated defragmentation tool hard drives, and also consider a new interface for managing external devices Device Stage.
Creating a homegroup will take a few seconds, after which Windows will generate a password that you will need to add other computers to the homegroup. Since this difficult-to-remember password will need to be entered on all computers that will be joined to the homegroup, for convenience you can print it using the link posted right there. You can't specify your own password at this stage, but you can change it later in your HomeGroup settings.
After clicking the "Done" button, the system will open the homegroup settings window, where you can change the sharing settings different types data, view the password or change it.
If you wish to change your password, please note that before doing so, you must ensure that home network There are no computers that are in sleep or hibernation mode. After changing the password, you will need to change it on all computers connected to the homegroup. That is why it is much more convenient to change an automatically generated password immediately after creating a homegroup, even before you join other computers to it.
Joining a homegroup is done in the same Network and Sharing Center window. After a home group has been created on the local network, on other computers in the “View active networks” section you will be able to see the “Ready to join” link. By clicking on it, you can specify which resources of this computer you want to share. After this, you will need to enter your homegroup password.
If you need to join a homegroup additional computer, and you forgot your password, you can always view it on any of the computers that are part of the homegroup. To do this, go to your homegroup settings and click on the “Show or print homegroup password” link.
If, when you join your computer to a homegroup, you receive a message that the password is incorrect, but you are sure that you entered it correctly, the reason may be due to the date and time settings. According to the official message published on the Microsoft website in the user support section, this error occurs when the date and time settings on homegroup computers do not match. The computer that you want to join the homegroup must be set to the same date and time as the PC on which the homegroup was created.
Once computers are joined to a HomeGroup, they will be visible in Explorer under the HomeGroup section, and all users can quickly access files that have been shared.
Using context menu Explorer, you can quickly manage the resources that will be open to other users connected to the home group. Right-click a folder or library and select the "Sharing" submenu. After that, you can open the resources for reading or for reading and writing for homegroup users.
Note that since HomeGroup is a simplified mechanism for sharing files, it does not provide for setting access rights for each user separately. For more fine tuning restrictions, you must go to your sharing settings and manually specify who can view or change files.
A computer cannot be connected to multiple homegroups at the same time. If you want to join another homegroup, you must first leave the first one. To do this, you need to open the home group settings window and click on the “Leave the homegroup” link, and then confirm your desire to do this.
The HomeGroup feature is not available if the system settings indicate that the computer is connected to an office or public network. If you need to temporarily connect your computer to a homegroup (for example, you took home a laptop that you usually use in the office), you must first change the network type, after which you can become part of the homegroup and gain access to home network resources.
Using the homegroup feature, you can not only quickly access files stored on other computers, but also streaming data over the network. This feature will be useful, for example, if digital photo frames, modern TVs, Wi-Fi streaming radio receivers and other similar devices are connected to your home network. To enable data streaming, you need to check the appropriate box in the homegroup settings, and then decide on some parameters.
First, you need to choose a name for your media library. Under this name the library will be displayed on other computers on the network in Windows Media Player in the "Other Libraries" section. You can then configure your access settings. The "Select default settings" link opens a window in which you can specify Common parameters access, and if you click on the “Configure” link next to each device on the network, you can set your own settings for each computer.
You can quickly block access to shared files multimedia for a specific computer.
⇡ Quickly connect to available networks from the system tray
In the first article of our series (see “The Hidden Potential of Windows 7: Installing New Windows”) we already talked about the improvements that have occurred in the notification area. One of them directly concerns working with the network. Now, when you click on the "Network" icon, which is displayed by default in the system tray, you can see a list of all networks available for connection, including wireless, corporate, mobile broadband, etc.
By clicking on the name of a network, you can immediately connect to it and just as quickly disconnect from it. The View Available Networks menu also shows all current connections for of this computer, and there is also a link to quickly open the Network and Sharing Center.
The ability to quickly connect to the network is especially convenient when working with a laptop, because using it in different places, you constantly change the Internet connection settings.
I once went to the Control Panel in the Network and Sharing Center and saw this picture - the page could not be loaded:
I decided that some system files were damaged, opened the command line as an administrator and ran the scan with the command sfc /scannow but the scan suddenly ended at 18% with a notification that the scan was completed and found damaged files which could not be restored. For Windows 7, if the necessary updates are installed, there is another way to restore system files using the command DISM /Online /Cleanup-Image /ScanHealth- it immediately scans and restores system files(in Windows 8 and 10, to restore system files, the last key should look like this - /RestoreHealth). The picture below shows the three commands that I executed and, accordingly, the results of their execution:
In general, DISM rustled, restored something, after which the Sfc check still reached 100% and completed, but the damaged files were still there and the Network and Sharing Center still did not open, complaining that the page could not be loaded. There are several more options for restoring system files and the system in particular:
- rollback to one of the previous restore points,
- recovery from image,
- attempting to restore from the recovery console,
- reinstalling Windows in update mode.
For some reason, there were no restore points or pre-created images on this computer, so the first two options were not available to me; in order to restore system files from the console, I would need bootable flash drive, boot from it and after selecting the language you need to select at the bottom left of the window:
And then this window will appear:
In it you can try the options marked with numbers 1 and 2, and in the first case - all files will remain in place, in the second - you will receive a system with the state as of the specified date, so everything necessary files on the system disk you need to copy it somewhere in advance. My third option is to launch the command line and write in it: sfc /scannow /offbootdir=D:\ /offwindir=D:\windows- where D is a letter system disk, the easiest way to find out is by typing in command line Notepad - notepad will start, in it you need to go to the file menu -> open and determine the drive letter with installed Windows, and substitute her into the team above. But in my case, this command also failed, then the last option remains after it is completed, I run it again Sfc /scannow this time everything is fine, the system files are restored.

We continue to dismantle the operating room Windows system 10. Today we will talk about the network and sharing center, where you can set up the Internet, Wi-Fi, or create a new connection. There are two ways to get to the Network and Sharing Center. The first method is in the taskbar, in the lower right corner of the screen, right-click on the Internet icon or Wi-Fi indicator. In the window that opens, click on the value – .
The second method is to click on the Start button in the lower left corner of the screen. In the window that opens, click on the tab - Options.
On the Network and Internet page, on the Wi-Fi tab, at the bottom of the page, click on the tab - Network and Sharing Center.
In the Network and Sharing Center, you can:
– Create and configure a new connection or network. Set up a broadband, dial-up, or VPN connection. Setting up a router or access point.
– Troubleshooting. Diagnose and fix network problems or get troubleshooting information.
From the Network and Sharing Center, you can also change the adapter settings. On the left sidebar, click on the tab – Change adapter settings. On the page that opens, right-click on the connection you need. In the window that opens, you can use the following commands:
– Disable connection.
– Find out the status connections.
– Tune bridge.
– Create label.
– Delete connection.
– Rename connection.
– View properties connections.
In the Network and Sharing Center, you can - Change advanced sharing options, to do this, click on the corresponding tab in the sidebar. Here you can set the settings for private network, guest network and public network. For example, if you are using a public network, then it is better to - Disable network discovery And Turn off file and printer sharing. Because enabling these settings on a public network may pose a security threat to your computer and all the files on it.
After setting the parameters - Save the change.
Microsoft continues to actively improve Windows 10, introduce new features and change the interface. One of the directions of these changes is the abandonment of the classic “Control Panel”, which was previously used for Windows settings, and move to the more modern Options menu.
For example, previously, in order to open the Network and Sharing Center, you had to right-click on the network connection icon on the taskbar. This method until recently it worked in Windows 10, but for latest versions it is no longer relevant. In this regard, many users have a question about how to open the “Network and Sharing Center” in new Windows versions 10.
In fact, the “Network and Sharing Center” opens almost the same as before, but now you just need to make one extra click. To do this, right-click on the network connection icon on the taskbar and select “Open Network and Internet Settings” from the menu that opens.
As a result, the “Settings” menu will appear in front of you with the “Network and Internet - Status” section open. Here you need to scroll to the very end of the page. Almost at the very bottom there will be a link “Network and Sharing Center”. By clicking on this link you will have access to the “” section you need.
In addition, the “Network and Sharing Center” can be opened using the command “control /name Microsoft.NetworkAndSharingCenter”. To do this, press the combination Windows-R keys and in the window that opens, execute the specified command.
If you wish, you can even make a shortcut that will execute the command “control /name Microsoft.NetworkAndSharingCenter” and thereby open the network control center. To do this, right-click on the desktop, select “Create – Shortcut”, enter the command and save.
