How to use remote access. How to set up remote access to a PC? Detailed instructions

Since our site is designed for average users, some disagreements arose within the non-Oshibka.Ru team regarding the usefulness of this article. Typically, such material is intended for more experienced users who at least have a good knowledge of the Windows OS.

On the other hand, what should a novice user do who has only a vague idea of what RDP, TCP, UDP are? But you really want to know? Again, is this necessary for the average user? Maybe one simple program is enough for him?

It's a difficult situation.

Explain in one article what it is remote access to a computer via the Internet, but in such a way as not to frighten off the visitor.

We decided to experiment. Talk about difficult things as clearly as possible. We will take your comments into account.

What is this article about?

This article will tell you about two types of remote connection, briefly tell you what it is ID. Will tell you about the programs Remote access And Remote Desktop. We will also try to configure your computer in order to access it remotely without using third-party programs. Complex terms in the article are highlighted in brown and provided with explanations in the form of tooltips.

Remote access concept

Remote access to a computer via the Internet is called means operating system, or third party program, allowing you to gain visual or file access to a computer located at a remote distance, but still connected to the Internet.

How is the required computer identified on the Internet?

Conventionally, all remote access programs can be divided into two groups according to the type of connection:

Using ID
Using IP addresses And domain names

Remote access programs using ID

Of great interest are programs that use ID (unique identifier). Receipt method ID something like this: when a remote access program is launched on the computer to which you plan to connect, it sends a request to its server through which the connection will occur.

Having received this data, the server generates for the computer unique identification number — ID. This number is assigned to the computer. In the screenshot below it is highlighted in red.

Knowing this identification number and password, you can connect to a computer from anywhere in the world with this ID.

It remains unchanged until the hardware is replaced or the OS is reinstalled.

So using such programs is very convenient. When you change Internet provider, city, and even country, your computer ID will not change.

Lack of programs using ID one - they are paid or shareware. Condition - you must not use the program for commercial purposes.

Example of programs using ID— TeamViewer, Ammy Admin. But the list is not limited to these two. They are simply the most popular and always heard by users.

We will not spend a lot of time on these programs, since their interface is simple and allows you to learn the program in 5-10 minutes. We may look at each of them in the future.

You won't have any problems with these programs. Use it for your health without overusing it. If TeamViewer will connect to a large number ID- then sooner or later, the communication session will be limited to five minutes.

Remote access programs using an IP address or domain name

With this category everything is a little more complicated. They need a static IP address or domain name. Connection via IP address, this is a classic connection type. It does not allow as much flexibility in the location of the computer and is most often used in "office space".

In order to use it, you need to do the following.

Connecting a fixed IP address or domain.

You need to connect with your provider additional service — Fixed IP address . This service is provided by many providers, including mobile ones. This service will assign your home network an external IP address in the format 123.123.123.123

It is this address that will allow you to find your computer from outside.

An alternative to a fixed IP address can be the service DynDNS. When registering, you will be given a custom domain, for example:

neoshibka.dyn.com

Next, you simply install a program on your computer that, when turned on, will track your current IP address and send it to the server DynDNS, which in turn will match your current dynamic ip address , with address yourlogin.dyn.com

Thus, no matter where you are, no matter what provider you use, no matter how often your IP address—the address of your computer—changes, yourlogin.dyn.com

We won’t undertake to say, but getting a fixed IP address from a provider is somewhat easier and cheaper than using DynDNS. For example, at the time of writing this article, the cost of a dedicated IP address was only 20 rubles. / month

Opening a port to a target - a remote computer.

Even now, knowing our IP address or assigned to us DynDNS domain, we can hardly connect to the computer - the firewall will not let us through. Most likely the port 3389 used by the program Remote Desktop which we will tame in this article will be closed. For everything to work as it should, we will have to open it and redirect it to the desired computer on the network.

Difficult? Not at all. Let's try to figure it out in practice.

Remote access to a computer via the Internet using Remote Desktop

So, first what we did was get a fixed ip address from our ISP. Let's remember, write it down, draw it.

Second. Let's find out intranet IP address our computer. To do this, we will follow the following path: Network and Sharing Center => Local Area Connection => Details
As you can see in the screenshot, the address of our computer within the network 192.168.1.102

Third the point will be opening the port 3389 to the above address. To do this, let's go to the router. In our case it is ADSL modem TP-LINK. We will show everything using his example. There’s nothing you can do about it, but you can’t do without instructions if you don’t know how to configure the modem yourself.

In our case we enter through Google Chrome at the address 192.168.1.1 and under the combination admin/admin. We get to the information page.

Let's go to Advanced Setup => NAT => Virtual Servers and press the button (add).

Here you can choose ready-made services or create your own.

We will create our own and call it Udalenka, but the name can be absolutely anything. We register the local address of the computer, the one we spied earlier. In the table we enter the port everywhere 3389 and select the protocol TCP/UDP. We do all this based on a standard Windows application. Remote Desktop. For other programs, the ports may be different. A good list of applications and the ports they use is provided. (What we are learning may even be useful for games).

If, for example, you want to use Remote Desktop, and advanced RAdmin, then you will have to register a different port for it: 4899 .

Press the button to save.

Item fourth, we will run on the computer we are going to control - Terminal Server Service. It’s worth clarifying something here.

Using the method described below is not recommended from the point of view of licensing purity if you do this in the organization where you work. Not sure about Windows 10, but in Windows XP - 7, the license was not violated if only one user connected to the computer.

We do all this for the purpose of familiarization and in order to learn the principles of remote access to a computer via the Internet.

So, to run it on your computer Terminal Server Service. In Windows XP this was done simply - Go to Administration — Services and applications — Services found it and simply turned it on. This allowed one user to connect to the computer. In this case, the user who was sitting locally was disconnected.

In Windows 10 we need to do things a little differently. We need a special patch. You can download it from here. This patch will allow you to run on the system Windows 10 terminal service.

IN lately, search engines Google and Yandex began to consider this file as a virus threat. In fact, the file lay on the site for two years, and not a single scanner ever considered it to be malware. However, the file is now stored outside of notOshibka.Ru - you download it at your own peril and risk.

Let's unpack the downloaded file to any location. For example on Desk. Run as Administrator file install.bat

A black window will indicate a successful result. command line with this content:

Fifth In this paragraph, we will set a password for our user, and also add him to the group.

For this purpose on the icon Computer and right-click to select Control.

In the window that opens, on the left side, we need to expand the list Local users and groups, select sub-item Users.

In the list of users, you need to find yourself and right-click.

Enter your password twice, press and the system will confirm that the password has been set.

Now we need to add our user to the group Remote Desktop Users.

To do this:

Right click on the user - Properties.

In the window that opens, go to the tab Group Membership and press the button <Добавить…>

Next, do everything in the same order as in the screenshot:

As a result of the work done - Remote Desktop Users should appear in the general list of groups to which the user belongs.

We would like to draw your attention to the following. The above describes how to assign a password to your user. But it’s better to create a new one and add it to the groups. Otherwise, you may end up losing some data. For example, we logged out wherever possible. I had to enter all the passwords again.

Let's check if we were able to gain remote access to the computer via the Internet using Remote Desktop.

We go to another computer, go to START menu => All programs => Accessories and run the program "Remote Desktop Connection".

Enter the IP address previously assigned to us by the provider into the window that appears, click the button <Подключить> .

If we did everything we did earlier correctly, then we will be asked almost immediately Name And Password user on Remote machine. Enter them and don't forget to check the box to remember your credentials.

And the last “security touch” will be checking the Remote Machine certificate. Here, too, you need to agree with everything. And also check the box.

That's it. If everything works as it should, you can go through the Remote Desktop program settings. Here you can turn on/off the sound, change the picture quality, connect local resources to the remote machine.

Remote access to a computer or “remote”.

Remote access or “remote work” (Not to be confused with Remote work.) allows you to sit at one computer via the Internet, see the screen of another computer and even work on it. Move the mouse across the screen, open folders, install and configure programs. Keyboard presses will also be transmitted via the Internet to this computer. Thus, while being far from the computer, you can perform on it various works – .

This way of working on a computer is especially loved by accountants who sit at home and work 😉

Now let's look at it technical details using Windows computers as an example. To organize remote access to your computer, you can use:

standard Windows tools called RDP
third party software VNC, r, and others.

The standard remote access tool for Windows involves a direct connection to the computer. That is, if the remote computer is located on an internal local network (that is, the Internet accesses it through a router), then you can organize access to this computer from the Internet by setting up the router. ……

How to make remote access via RDP?

For remote access to a computer via RDP to work, you need to:

so that this computer can be directly accessed from the computer from which the connection is supposed to be made. Those. both computers must be on the same local network or the router must be specially configured for this (see port forwarding)

enable remote access on your computer. Right-click “My Computer” and select “Properties”. Next is the “Remote Sessions” tab. Check the “Allow remote access to this computer” checkbox. The user under whom the RDP connection will be made must have a password!

After completing these two steps on the computer, open the client for remote connection via RDP, enter the name of the remote computer (or IP address) and connect. How to open the RPD client? The client opens like this - click “start”, “run” and enter the command: mstsc and press Enter. Or look for the “Remote Desktop” item in the Windows menu.

The question is, of course, rhetorical, in our enlightened age, the “age of computers”, most users know what it is remote access to a PC and what it is needed for, for those who don’t know, I’ll try to briefly explain. Remote access to a computer makes it possible to control another or other computers (if there are several of them) at a distance, via the Internet or local network, exchange files and data, install software, configure a PC from a distance.

There is probably not a single enterprise, organization, institution, or office left that does not have remote access to computers. This is usually done by a sysadmin (system administrator). Employees do not need to run from office to office with flash drives to copy/transfer data and files; everything is done through a computer. And the boss (manager) can always control the actions of his subordinates at the computer - whether they are visiting social media and other sites during business hours.

For ordinary users, remote access is also very useful. You can help fix or optimize a system to a person who doesn’t understand it from a distance - after all, it’s better to do it yourself once than to explain it 10 times to someone who doesn’t understand. In addition, transfer photos and videos to friends and family while on a business trip or vacation, gain access to the necessary files from anywhere in the world, work on an office computer while at home, etc.

You can get remote access using programs for remote administration, and setting it up in Windows OS. In my opinion, it’s better to control another computer from a distance using programs - it’s faster and more efficient, and many of them support voice chat.

If you want to set up remote access in Windows, go to Control Panel- System - Deleted sessions

and configure Remote Assistance And Remote access permission

Remote administration programs

The most common and well-known programs for remote administration and gaining access to remote computers are Radmin, Virtual Network Computing (VNC), TeamViewer And Ammyy Admin.

Using Radmin Server And Radmin Viewer You can simultaneously connect to several computers both via a local network and via the Internet. The program is easy to use and provides high level security and high speed work. The program can be used free of charge for 30 days.

By using TeamViewer In real time, you can control the desktop of a remote computer via the Internet from anywhere in the world, send and receive files, make presentations and help colleagues, friends and family. To do this, you do not need to know the external IP address - just know the ID and have an Internet connection. The program has a strong encryption algorithm, is also portable and free for non-commercial use.

Simple and intuitive program interface Ammyy Admin will help you connect to a remote PC via the Internet and control it knowing the client ID or IP, even for an untrained user, everything is simple and clear. The program is also portable and reliable. Free version for non-commercial use allows you to use the program 15 hours per month, which in principle is quite enough for ordinary computer users.

Control another computer via the Internet or LAN using the TCP/IP protocol using VNC very convenient, because The program is cross-platform and allows you to remotely access a desktop with another operating system installed. It is also possible to control the computer from a phone (smartphone). The free version of VNC does not support session encryption.

Using these and others, you can organize remote access, exchange files and control other (remote) computers at a distance.

Useful tips for computer dummies

Remote connections have become widespread relatively recently. This is due to the development of local networks and the emergence of Internet access in large and medium-sized populated areas. About 10 years ago, you couldn’t even dream of connecting to a computer that was located several tens or hundreds of kilometers away.

But, nevertheless, the idea of connecting to a computer at a distance was tested while working on local networks. And one of the reasons for the development of this feature was human laziness (or convenience). Let me give you an example. A certain system administrator has 30 computers on his local network, which are distributed among office rooms. large area or on different floors. During their work, users regularly have questions about the operation of programs, equipment, and information search. The network administrator has to leave his office every 10-15 minutes. workplace and help users, even if the problem is minor, because even with a phone, sometimes it is not possible to correctly identify the problem and recommend a solution. But if there is a configured remote connection to user computers on the local network, the system administrator can, without leaving his seat, solve the problem fully, since he will see and control the user’s computer independently.

In a situation where computer users are located in different parts of the city, in addition to convenience, the ability to remotely connect to computers will bring significant savings to the organization cash for transportation costs and release of the driver for other company needs.

Connecting to a computer on a local network

Let's consider next case. There are several computers on the local network, each of which has its own IP address and name. ()

The task is as follows: connect from computer 192.168.1.2 (it) to computer 192.168.1.4 (buh3).

Without using the Internet, this can be done using a remote desktop connection or through the RAdmin program, which is very popular, despite the paid license.

Remote Desktop Connection

First of all, you need to open the option to connect to the desktop on the computer you will connect to (in the example “buh3” with IP address 192.168.1.4).

If the computer you want to connect to has the Windows 7 operating system installed, or one of the Windows Server 2003 or 2008 server platforms, then you must:

Right-click on the “Computer” icon on the desktop and select “Properties” from the menu that appears.

In general, set the switch to be able to connect with any version of Remote Desktop.

Click the “OK” button in the system properties window.

If Windows XP is installed on the connected computer, then the procedure for opening access to the desktop is as follows:

Right-click on the “My Computer” icon on your desktop and select “Properties.”

Go to the “Remote Sessions” tab.

Check the “Allow remote access to this computer” checkbox and click “OK”.

Note: if there is no “My Computer” or “Computer” icon on your desktop, then look for it through the “Start” button (lower left corner of the Windows desktop).

After the remote computer is configured, go to the computer from which you will connect. You need to start a remote desktop connection on it.

For Windows 7, follow these steps:

Click the “Start” button in the lower left corner of the Windows desktop.

Open the “Standard” group.

Launch the “Remote Desktop Connection” shortcut.

In the “Computer” field, enter the IP address or name of the computer to which you will connect.

Click on the “Connect” button. When an authorization request appears, enter the name and password of the user on the connected computer or domain user (if a domain is organized on your network).

Starting a Remote Desktop Connection in Windows XP is slightly different than in Windows 7.

Click the Start button.

Open “All Programs” (or “Programs”).

Expand the “Accessories” group and launch “Remote Desktop Connection”.

As for Windows 7, enter the IP address or name of the computer you will connect to and click on the connect button. When connecting, you must enter the user name and password available on the computer or domain.

If, when you try to connect, you receive a warning that the computer you are connecting to does not have a certificate, continue the connection by answering the question in the affirmative.

After establishing a connection to the remote desktop, you will be able to control your computer from a distance. In this case, the user sitting directly at the remote computer is blocked from access and control is intercepted. He doesn't see what you are doing. To regain control, the user must unlock the system by pressing the Ctrl+Alt+Delete key combination and entering his Windows name and password. Another remote user who connects to the computer later can also take over control.

The Remote Desktop-based control method is not very convenient for providing assistance, since your interaction with the user does not occur online. But such a connection is ideal for working on a remote computer on which no users are working. These can be servers, or your own workplace, located in another room.

Connection using RAdmin program

The RAdmin program consists of two parts: Server and Viewer.

The Server component must be installed on the computer to which you will connect. If you have many computers on a local network to which you periodically need to establish a connection, then this component must be installed on each computer. After installation, the RAdmin server icon appears in the system tray (lower right corner of the desktop). Through it you can access the component settings, where you need to set a name and password for the connection. The figure below shows the sequence of creating a user, password and assigning rights for the RAdmin server part.

The Viewer component is installed on the computer from which the connection is made. This is usually the system administrator's computer. Having launched the Viewer component, create a new connection, specify the address of the computer to which you are connecting and enter the name and password specified on the Server component side.

Connecting via RAdmin makes it possible to work on remote computer in full interactive mode, i.e. everything you do is displayed on the screen of a connected computer online. In addition, you can send text and voice messages to a remote computer, as well as transfer files.

Connecting to a remote computer via the Internet

The process of connecting to a remote computer via the Internet is carried out in the same way as for a local network, if the connected computer has a dedicated external (or “white”) IP address. But in modern networks this is extremely rare, since the connection via the Internet is not made to a single computer, but to another local network, and already in it to a specific computer. The entry point in a remote network is a router or gateway, through which you will be taken to a remote local network and will be able to access local computers.

All computers on the remote local network have internal IP addresses and do not have dedicated external ones. Only the router has a dedicated external IP address. This is where the connection should be made. But in order to connect to the router and go to the desired computer on the local network, you need to configure port forwarding on the router (“port forwarding”).

Redirection works as follows: You connect to the external IP address of the router, specifying in addition to the address the port for connection. Depending on the port number, the router (in accordance with the redirection settings) transfers your connection to a specific computer on the remote local network. Setting up port forwarding requires some knowledge of networking and depends on the router model.

Having working port forwarding on the router, you can connect to a remote computer that is part of a remote local network using the methods listed above: connecting to the desktop and using the RAdmin program.

Connecting using TeamViewer

TeamViewer allows you to quickly connect to a remote computer and does not require special knowledge building networks and their settings. This is a convenient option for most users.

The program works when there is an Internet connection. The computers are connected via the TeamViewer server. Where are computers physically located and how are they arranged? local networks, doesn't matter.

There are several versions of TeamViewer, the most popular of which are:

TeamViewer: full version. It has the ability to both establish a connection to a remote computer and allow you to connect a partner to you.

TeamViewer QuickSupport. It can only be connected to your own computer. Launched by the user separately. Connection from outside is only possible if the program is running.

TeamViewer Host. Only connection to your own computer, starts when the operating system starts. Used in cases where it is necessary to connect to a remote computer without the approval and confirmation of the computer user.

Let's look at the connection process through the TeamViewer program. On the computer from which the connection is made, you must install full version TeamViewer. On the remote computer you need to install either the full version or the Host version, or save the TeamViewer QuickSupport launch file ( this version does not require installation).

After logging in, you will be able to work on the remote computer interactively. The user will be able to see everything you do, as well as take any actions independently.

TeamViewer is free for private personal use, but companies will have to purchase licenses to use it.
