Unable to allow xp sharing. Internet Connection Sharing cannot be enabled LAN connection already set to use

Q: Internet Connection Sharing cannot be enabled. The LAN connection is already set to use

Answer: Runner0910,
your provider (probably intentionally) gives you an IP in the same range 192.168.137. *, in which Vin usually assigns an address when "sharing".
You need to disconnect from the Internet, then share "Local Area Connection" to "Local Area Connection 2", then go to the TCP / IPv4 properties "Local Area Connection 2" and change 192.168.137.1 to 192.168.0.1,
then connect to internet

Q: Internet Sharing won't turn on

For the second or third day I can not turn on Internet sharing for Virtual WiFi. The bottom line is that a window pops up with a warning that the shared access is already in use for "ethernet_14". What ethernet_14 is, I have no idea. Then a window appears that the new settings will be applied the next time you connect, and then a window with an error.

Answer: insect_87, windows updated and this problem is gone. But there was a problem with COM Surrogate. I turn on the general access - on the laptop from which I distribute, it writes that there is Internet, on devices (smart on WM10 and tablet on Android) it writes that there is no Internet. I'm trying to turn off sharing, to try turning it on again, it says "COM Surrogate has stopped working", then the "An unexpected error has occurred" window, and the "Network Connections" window hangs tightly.

In general, the conclusion: Windows 10 is not ready to distribute the Internet so easily.

Question: No access to the server by external ip through the local network

Answer: And now, in fact, everything worked, but after one, well-known place ... So next to the server there is a computer on it, a constant ping of the server is running and it gives out "waiting interval exceeded", in general it does not reach. At this moment, a copy of the existing Internet connection is created on the server and .... PING APPEARS and all access via external IP. At the same time, the connection is stupidly copied by the "create a copy" button, it is not connected or configured, just a banal and stupid copy of the existing one is created.

From now on everything works. I watched the difference in routes when creating a copy - it is not there. So how to leave this state of affairs, because rebooting kills access again ... even if there are no special options, then maybe there is some command to create / delete a connection from the command line? I know there is a connection, because I use it, but creating / deleting ...

I still don’t catch what the joke is ... I even rearranged Windu and re-configured it to a minimum, but still the same canoe.

Question: How to share Internet access

About networking, I can say that in the address type of our computers it says "Assigned by DHCP". I installed the modem on my computer. Also, according to the instructions, I created a new connection. As a result, my computer began to access the Internet, but at the same time I lost the ability to access shared network folders, and my email stopped working. When you disconnect your internet connection, everything works again.

Thus, I cannot normally (without violating access to the internal network) access the Internet on the computer on which the modem is installed. Therefore, while I have a question, is it possible in my situation to organize access to the Internet without disrupting access to the network?

P.S. If I did not provide enough data for an answer, then write about it, because I do not know what might be needed for a solution.

Answer:

Additionally on your computer (so that it becomes a router):
1. start the "Routing and Remote Access" service, start mode - "Auto"
2. in the registry branch HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Services\Tcpip\Parameters
set the IPEnableRouter parameter to 1

Question: Shared access to the Internet (an RNDIS device was connected to a computer in LAN)

P.S. Why do I give an ip to another subnet: if I give an IP from the office network, then NDIS1 will receive an IP, but the device will not be "seen" in the office network. And why - HZ.

Answer: Sekns, he wouldn’t have done it himself, it’s reasonably logical. I will test

What is Internet Sharing?

Internet sharing for organizations is the most common solution. However, there are times when large organizations do not have a shared Internet. More precisely, there is no single and common Internet access for the entire organization, for example, some departments work through a dedicated line, and some employees use dial-up access modems to access the Internet. But there are more deplorable situations, when the system administrator does not even know that some department ordered and uses a special leased line.

Pros and Cons of Shared Internet Access

Naturally, Internet Sharing helps an organization keep its Internet costs under control and, most importantly, keep the network secure. Generally speaking, the unauthorized creation of Internet access channels by users should be prohibited not only by administrative, but also by technical measures. The network administrator must know what connections and channels exist in the corporate network, and especially where it is open to exchange information with the Internet, in order to protect the network from threats emanating from the Internet.

Thus, further we will consider the situation when an organization has one or more centralized Internet connections through which all employees of the organization have a common Internet access. Situations of confusion in Internet connections are clearly not normal and should be resolved first of all by administrative decisions.

The general Internet in the organization has a number of significant advantages. This is first of all:

1. the ability to control the Internet - all information flows incoming or outgoing from the local network of the organization.
2. the ability to install firewalls on the path of all incoming and outgoing IP packets to provide centralized network protection.
3. the ability to control the total expenses of the organization on the Internet.
4. the possibility of general accounting of traffic and control of user behavior on the Internet for the entire organization.
5. More efficient use of funds: two slow channels at the provider usually cost more than one fast one, traffic with large consumption volumes can cost less. In addition, the so-called statistical multiplexing allows you to use the resources of the Internet channel for sharing more efficiently.

All this does not mean that the organization should have one Internet channel. There may be several of them, but the general Internet access assumes their centralized management, when all channels are considered as a single pool through which the general Internet access is carried out.

Speaking about the advantages of general Internet access in an organization, it is necessary to say about the difficulties that are present in it. The complexities are usually related to the fact that all users have a common access and, therefore, influence each other. In practice, it often happens that a large file download started by someone can take up all the resources of the common channel and prevent, for example, the accounting department from making an electronic payment. Thus, for the general Internet, the tasks of monitoring, accounting and managing user access become extremely important. In other words, those features that are mentioned as the benefits of general Internet access become necessary to implement!

How is Internet Sharing?

In order to understand how the tasks of traffic accounting, user rights management, and network security can be solved, it is necessary to understand how general Internet access works. Let's consider some scenarios of the organization of the general Internet access.

Shared Internet access for local network

In the simplest case, an organization's corporate network is a single local area network that is connected to the Internet via a dedicated line, an office building Ethernet network, or a home network. In this case, most often, the LAN switch includes channel equipment: xDSL modem / router or PPPoE / PPTP router that works with the provider's office or home network.

The administrator's ability to manage and control such a network will be limited by the settings available in the modem/router. As a rule, these are rather cheap devices, the control capabilities of which may be limited.

Corporate network with distributed offices and a centralized channel

In this case, the organization has its own private network, ordering leased lines between its offices and combining their local networks into a single routable space. One of the offices, well located geographically, becomes the center where the Internet channel is laid from the provider. As a rule, in this case, the routing equipment for combining the local networks of individual offices has advanced management and accounting capabilities. Also, organizations with such a network structure install separate systems - Internet control servers in order to solve the problems of traffic accounting and user access control. Internet Control Servers give IT staff greater flexibility and help leverage the powerful features of routing equipment. For example, turning a report on the consumption of traffic by IP addresses into statistics for specific users. Network protection can be implemented by separate specialized devices or be one of the functions of the Internet control server. Rational use for general access of the main and backup Internet channels can also be provided by the Internet control server.

Routed corporate network with distributed Internet channels

Such a network automatically appears in an enterprise that combines the local networks of its remote sites by renting channels from an Internet provider, i.e. building a so-called virtual private network. Except that each office can get its own Internet access, this scheme is no different from the previous one. When entering into an agreement with a provider for a leased line, the client, as a rule, can choose whether this line will be routed to the Internet or not. However, from a topological point of view, it will often be more profitable not to drive Internet traffic to one central office, but to receive Internet access in each office. How, then, to make Internet access common, and not scattered and unmanaged?

You can also solve this problem using a set of Internet control servers in each office where there is an independent Internet channel. For the administrator of such a network, the management of general Internet access from all offices in this case will be transparent and convenient.

Thus, the optimal solution to the problem of setting up managed shared Internet access in all cases will be to use an Internet control server - one, in the case of one local network, or a single Internet channel and several, if Internet channels are available in geographically remote points of the company's network.

Setting up sharing

On the example of using A-Real Internet control server developed by A-Real Consulting.

Shared Internet on a local network with one Internet channel

Initial conditions: ADSL line from the provider, ADSL modem broadcasts the WAN interface of the ADSL modem. Inside the local network, "gray" addressing is used, for example 10.0.1.0/24.

To set up general Internet access, you must enable the internal interface of the A-Real Internet control server in the port of the LAN switch. On the internal interface of A-Real Internet Control Server, set the IP address and mask of your local network, for example, 10.0.1.254/24. On the external interface of the A-Real Internet control server and the LAN interface of the ADSL modem, set "gray" addresses from a different range, for example 10.0.255.1/24 and 10.0.255.255/24 respectively.

Further, if your network uses a proxy server, you can transfer its task to the built-in proxy server of A-Real Internet Control Server. To do this, simply configure the proxy server address on the browsers of computers on the local network: 10.0.1.254 port 3128.

• For example, by clearly linking users to computers, you can set up the simplest scheme on A-Real Internet Control Server - by IP addresses. Naturally, in this case, measures must be taken to ensure that users cannot change their IP addresses on their own, for example, not to give them administrative access to computers.
• Authorization on the proxy server. You can give users individual logins and passwords to access Internet resources through a proxy server.
• Authorization via windows domain controller. A-Real Internet Control Server can obtain user information from an Active Directory domain controller, in which case the user will only need to log into the windows domain with his password in order to get general Internet access through A-Real Internet Control Server.
• Authorization through a separate program. If the use of a domain controller is not included in your plans, you can install a small program on users' computers, which is included in the A-Real Internet control server delivery package, which will request the user's login and password when accessing the Internet.
• Authorization via PPTP or PPPoE. You can set up a PPPoE or PPTP server on the Internet server so that users access the Internet through a VPN tunnel, which each of them's computer must establish with the Internet control server - each with its own username and password.

Internet Sharing via A-Real Internet Control Server

A-Real Internet control server is a ready-made software Internet gateway. It is installed on a dedicated computer connected between the local network and the Internet. A-Real

While setting up a laptop or computer to share the Internet via Wi-Fi on Windows 10, some users cannot share the Internet network. In this article, we will try to provide information on how to share a Wi-Fi network, what difficulties may arise and how to solve them.

The wireless communication function is very popular among network users. This process is carried out mainly using a Wi-Fi router. But sometimes it is not there or it is simply impossible to use it for some reason. In such situations, you need to know how to create an access point from a simple Wi-Fi adapter. After setting up Internet distribution in access point mode, it is not always possible to use the Internet, even connecting to the created network. This happens mainly due to standard settings that do not allow using the connection on connected devices.

The operation of the Wi-Fi virtual module in the tenth version of Windows is similar to the seven. The organization of the work of a wireless network without a router should assume the presence of WiFi technology, which is equipped in the adapter. This module is installed not only in routers and modems, but also in phones, tablets, laptops. As a result, the device can act as an access point. The launch of the access point is organized using the command line. After that, you can receive and distribute the Internet at the same time, but there is one problem - the network is turned on, but you cannot receive and transmit traffic to the Internet. This is because the sharing needs to be allowed. How to fix it? To do this, you need to know the connection with which the Internet is provided by sharing it with the Wi-Fi module.

This article is an addition to the instructions on . Therefore, if you have not done this, then it is better to first install everything according to the instructions. And if you have already created a Wi-Fi access point, but connecting to it leads to limited traffic transmission or no traffic at all, then this is due to some difficulties that can be quickly resolved. Let's try to consistently deal with the problems that happen in the sharing settings for the Wi-Fi network module in Windows 10 and how to solve them.

When opening a public Internet network not prompted to select a connection

This problem happens quite often. Its essence lies in the fact that when you start the Internet access point, in the window with adapters there is already " LAN connection 12” (the name can include any number) and now it remains to allow Internet connection specifically for this network.

• For you need to go to the connection properties: by clicking on the Internet connection icon (on the desktop at the bottom right) with the right button, select " Network Control Center..«.

• And then open the section " Change adapter settings". Here you need to click on the network icon (most often " ethernet") right click, click on " Properties” and then open the tab “ Access" and activate the line " Allow other users to use…..” But what if the lines " Home network connection" No? Shown here is only Wireless network“, because the menu does not drop out, which should contain the connection we need. In fact, it looks like this:

• There is an exit. To do this, open the properties of the adapter with which the network is connected. Then from the line " Allow connected network users to use the internet…» uncheck, and press « OK«.

• Then re-enter the properties of the adapter and return the checkmark to its place. After that, a menu will open below, in which there will be the necessary for us “ LAN connection 12(may be different). Then activate it with the button " OK«.

• The way to disable and enable the network adapter also works. To do this, click on the connection icon and select " Disable". After that restart.

The manipulations performed should lead to access to the Internet over the provided network for other devices.

If, nevertheless, the home network selection line still does not appear in the drop-down menu, then you need to check that the Internet network is really running, in the "Adapter Settings" there should be a network icon "Local Area Connection (in our case 12)" with the image of the active networks.

No "Access" tab in connection properties in Windows 10

To provide sharing, you must set the parameter in the Internet properties, but there is no necessary tab for this, the " Access«.

To correct the situation, do the following:

1. First you need to check the presence of the icon " LAN connection*". This can be done by opening Network and Internet", then " Network connections". If the icon is there, then the network is running. Otherwise, you need to activate it using the above instructions.
2. If only the " ethernet", then there will be no tabs" access "and the choice of connections to networks, because all connections are missing. The solution to this problem can be to install the driver on the virtual adapter and start it. If there is more than one network connection, then you need to install the driver and start it again.
3. There are times when the checkbox for permission to other users is ticked opposite the item “ Wireless network" in the properties of other connections, then you need to remove it and most likely the item " Access" in " ethernet' will appear.
4. If you have the "Starter" version of Windows 7 installed, then you will not be able to share.
5. When setting up the provision of Internet from a 3G modem, it happens that the item " Access" is absent. This is due precisely to the model of the modem itself and its settings.

When you try to connect from one Windows computer to another, you may see a message like "Windows cannot access // *computername*" that is located on the local network. The error often occurs on Windows 7 and 10, but can also appear on 8 and other less popular versions of the system.

Problem types and error codes

An error about problems connecting Windows to the local network sometimes appears on Windows 7 after installing one of the official system update packages. At the end of the window, in this case, an error code is given - 0x80070035. Most often, the problem is banal and caused by incorrect system settings on the computer (or on one of the computers), which is why all the problems with creating a local connection arise.

The error code message may look different:

1. Windows cannot access a computer on a Windows LAN (7, 8, 10, XP).
2. Permission to access 'computername' is missing. Contact your network administrator for access.
3. Windows cannot access a computer on the network (local or home network, computer, network drive).
4. Windows cannot access the computer. Check the spelling of this name.

Error codes that may appear after the message: 0x80070035, 0x80004005, 0x8007004b, 0x800704b3. It remains to figure out what each error means and how to get rid of the problem.

Error 0x80070035 "Network path not found"

The most common error, which says that Windows simply did not find the path where you can establish a connection. To solve the problem, follow a few simple instructions.

Examination sharing settings:

1. Right-click on the local drive that cannot be connected to.
2. Select the "Properties" item, in the window that opens, go to the "Access" tab.
3. Click "Advanced settings", check the box next to "Share this folder".
4. Make sure that the "Share name" field contains exactly the local drive to which you want to connect.

If the error continues to appear, you should try setting sharing a computer's IP address. This can help bypass the error and set up a connection directly using the resource's IP address.

This requires:

1. Click "Start", type cmd in the search and find the command line.
2. Right-click on the found application and run command prompt as administrator.
3. Type "ipconfig /all" (without quotes) into the command line field, press Enter.
4. In the field that appears, find the IPv4 address of the computer. It looks like 192.168.X.X.
5. In the Run window that appears, enter the IP and local drive in the format //192.168.1.1/F (where F is the name of the local drive).

If again nothing worked, and Windows still cannot establish a connection, it makes sense to check that the Device Manager is working correctly.

Job setup device manager:

1. Press the key combination Win + R.
2. Enter devmgmt.msc in the field and click "OK" to enter the device manager.
3. In the window that opens, click the "View" tab in the top menu.
4. In the drop-down menu, check the box next to "Show hidden devices".
5. In the list of all devices, find and click on the "Network adapters" list.

The list of drivers that appears should be considered in detail. Outdated and unused network drivers may conflict with new Windows software, especially after some security patches. To fix the connection problem, uninstall all old and unused drivers, and then restart your computer. The system should automatically install the new software version. You can manually update the available drivers for the displayed devices to avoid deleting the necessary files.

Correction of errors with account rights

Sometimes Windows cannot access another computer on the local network for quite commonplace reasons. Error codes 0x80070035, 0x80004005, 0x8007004b, 0x800704b3 and other notifications may well be caused by these reasons, so you should check for their absence.

1. Access rights are not set for the user from which the connection is being attempted. Make sure the user you are connecting to has administrator rights. The administrator account must be added to the list of allowed users.
2. Different passwords are set in the Windows Security dialog box. You should study the instructions for creating and distributing a local network and correct the errors found.
3. The user is not the owner of the files and folders that he is trying to distribute on the local network.

In order to become the owner of a folder or file, you need to:

1. Right-click on a file or folder.
2. Select "Properties".
3. Go to the "Security" - "Advanced" - "Owner" tabs.
4. Add the desired account to permissions.

In addition, you will need to give the added account full access. This is done in the tab "Properties" - "Security" - "Edit" - "Add". Only after these steps, you need to give this or that folder or files access to the local network. The error should disappear and Windows will establish the connection without any problems.

Solution for "Windows cannot access \\PC name" error

To fix a local connection error with this note, you need to perform a few simple steps with the folder you want to connect to:

1. Right click on the folder.
2. Select "Sharing" from the submenu.
3. Go to the "Specific Users" section.
4. In the window that appears, click on the triangular arrow next to the "Add" button and select the user for which you want to grant access. If users are not displayed in the list, you need to select the "All" item.

For the added user, you can set the access level: read or read and write. After that, you need to click on the "Share" button and, if no errors or notifications appear there, click the "Finish" button. The method helps on Windows 7 and newer. In XP, the interface may be called a little differently, but the principle of error correction remains the same.
