Error 868. Troubleshooting the 868 Error in Windows 7

One of the most common problems connecting to the Internet, whether it's a direct connection using a cable or using a private virtual VPN network with a Wi-Fi router, is when the system reports that an Internet error has occurred 868. Next, there are several basic ways to fix it For general cases. Let's take a look at the issue of fixing the failure when using the connection "Beeline", taken as an example (other operators and providers may have such a different number, but the essence of this does not change).

What does connection error 868 mean?

So, what does the user say about the message on the screen indicating this failure? Typically, when you connect to the Internet, error 868 signals that the network adapter was unable to initialize the IP address of the server through which the connection is made.

In the case of a VPN server, this connection is via PPTP or L2TP. However, the problem can be manifested equally in wired and wireless connections. Similarly, this situation is typical for almost all Windows-systems, starting with the "epsilon" and above.

The main causes of the failure

If we talk about why the error 868 appears, there are several main reasons:

• Technical problems with wired connection;
• Consequences of viral infection;
• Incorrect network connection settings;
• Restrictions on access rights;
• Blocking connections by third-party programs or Windows Firewall.

Troubleshoot technical issues

In order not to waste time, you should first make sure that the connecting cables are connected tightly and correctly. If using a wireless connection, make sure that the router is operating normally.

About the settings of the router is now not going. If you get an error 868 when VPN connection, you can try to just reboot the router. It must first be completely disconnected from the mains, rather than using the reset button, then wait at least a 10-second pause before turning it back on. Perhaps resetting the settings will help.

Scan the system for viruses

It can very well be that the connection error 868 is caused by the impact of specific viruses. As already understood, it is strongly recommended to check the system for threats.

It is desirable to use not a regular anti - virus scanner, but third-party portable utilities. It's best to use applications with the general name Rescue Disk to scan the system before it starts.

We check the activity and the correct connection

Now, before determining how to fix the problem, you need to check whether the system sees an active connection and the protocols used, in particular IPv4.

To test from the "Run" menu (Win + R), run the command line (cmd), where we register ipconfig / all, then the available connections and their parameters will be displayed. In the case of the Beeline operator, error 868 may manifest itself in such a way that the current IP address is invalid. So pay attention: it should start with 10. If there is no such item at all, or the address looks like 169.254.XX, you should try to install the official drivers for the network adapter or again check the cable connection density for the wired connection. Sometimes a problem can arise from the provider. However, in most cases, it concerns incorrect settings of the current IPv4 protocol, if IPv6 is not used (which is unlikely).

IPv4 configuration options

The 868 VPN connection or wired connection error is often corrected by changing the IPv4 protocol settings. But there may be several options.

In the simplest version, you need to go to the settings of the network management center. The easiest way to do this in the same "Run" menu is to immediately enter the command ncpa.cpl, then select either the adapter settings or the wireless connection, find the IPv4 protocol and go to its properties. Here, for the fields for obtaining the IP address or the address of the preferred DNS server, set the automatic mode.

In some cases, the provider can offer its own configuration. In this case, you need to enter all the values correctly. But most often the receipt of the address remains automatic, and the parameters are specified only for the preferred and alternative DNS server.

Configuring DNS Service and Permissions

If error 868 appears again, this may indicate that the user has simply been denied access rights. First, we enter the VPN connection or adapter settings , as shown in the previous case, and then go to the access tab.

Here in the first line on top you should remove the "bird" from the point of allowing the use of the connection by other users of the network. However, this only applies to cases where it is not necessary to "distribute" the Internet from this terminal.

Sometimes, either because of system failures, or because the administrator disconnects the computer terminal, the DNS service is turned off. So, it must be turned on. To do this, use the services.msc command from the same "Run" menu. A window with all services opens. Here you need to find a DNS client. By default, the service should be set to "Operates". If this is not the case, simply turn on the client and restart the computer terminal or laptop. In theory, after such manipulations, the error 868 disappears.

Perhaps the reason is in the firewall

Another reason for this situation may be the blocking of the connection by the antivirus program or Windows firewall. In general, you need to check whether port 53, which is used for the correct operation of the DNS client, is blocked.

If it is not specified in the settings, the port needs to be opened. This is done by creating a new rule, where all the necessary parameters are specified, following the instructions of the system. A lot of articles have been written about this, so there is not much point in stopping at such settings. However, if the user is not afraid to risk, the firewall can be turned off at all, and then see how the system will behave when trying to make a connection. True, it is possible to perform such operations, as they say, at your own peril and risk. On the other hand, if a powerful antivirus with a built-in firewall is installed in the system, then why not?

"Beeline Online". Error 868: Corrective Action

Finally, as for the operator "Beeline". Here, not everything is so simple. As a rule, the computer system can not determine the servers vpn.internet.beeline.ru and tp.internet.beeline.ru, which entails the appearance of a failure 868.

We look further. If, as mentioned above, the IP address starts with a value of 10 at check, everything is fine, you can proceed with the connection. In the connection window, pay attention to the address line on the Internet. Here it is necessary to correctly write down the parameters just mentioned.

If the reason is not this, it is very likely that you will have to change the IPv4 settings. At the same time we leave receiving the address in automatic mode, and manually correct only DNS server address settings: for the preferred one we enter four eights, for the alternative we have two eights and two fours. Yes, the common rule for all configurations is to disable the proxy for local addresses, unless another provider provides it.

Now it remains to pay attention to the firewall. Here you either need to unlock, or open ports 1701, 1723, 80 and 8080 (they are required for correct connection via "Beeline").

If nothing has helped

It happens that the above methods do not work. What to do? In this case, it is recommended to reset the settings. To do this, write the following at the command prompt:

• Netsh winsock reset;
• Netsh int ip reset.

After that, you must necessarily reboot the system, after which you can try to reconnect.

Conclusion

If we sum up the error in the consideration of the error 868, we can see that there are plenty of reasons for its appearance. The solution of the problem directly depends on each specific situation. However, general methods that were able to correct such a malfunction in any system, regardless of its modification or connection type, were shown above. IPv6 settings were not offered here only because it is still used very rarely, and the parameters you enter almost completely repeat IPv4 settings.

In addition, if the problem occurs on the part of the provider, there is nothing to fix it. In case of a sudden failure, when everything worked before a certain point, you can still advise you to restore (rollback) the system from the control point, at the time before the connection error occurred. Well, in the rest you can follow the above tips and recommendations. By the way, as for Beeline, this operator is taken solely as an example. For other operators, almost everything is configured in a similar way, only when you open the ports from the provider you need to know their numbers.
