"720 error". "Error 720" when connecting to the Internet

It happens that yesterday you normally used the Internet, and today you can not access the network. It would seem that everything is as usual, the login and password have been checked, the computer is being registered, but then a window appears in which "720 error" is displayed. This indicates that due to a protocol failure you can not access the Internet. Here, most users begin in the literal sense of the word panic. But this is the last thing you need to do, because this "disease" is easy and simple "treated", and now we'll see how. You will need about an hour of free time, patience and the desire to fix everything, as well as computer skills at the beginner level.

What needs to be done first thing?

The most important thing is to understand that this error is relatively rare. This is especially true for properly configured Internet connections. However, if you are unlucky, then first try such elementary steps as turning on and off the computer, restarting the modem, after all, you can call the helpline support service (for free) and leave your application there, having explained in advance What's the problem. But one thing is for sure: surely the trouble is that your operating system has somewhere a "hole", because of which the connection is distorted, and you, in fact, see the following inscription: "Code 720, connection error". But do not despair, now we'll figure out how to solve it without the help of professionals, which will save us some money. To do this, you need a little patience.

What is the cause of the error?

In all cases, this ailment is caused by incorrect parameters of the PPP protocol of your Windows operating system. It's worth noting that it does not matter which OS you use, be it Vista, 7 or even Win8. In 100% of cases, the whole fault is PPTP-protocols, which are either incorrectly configured, or completely absent, which, by the way, also occurs. At once we will notice that without certain knowledge to eliminate a problem it is difficult enough, therefore it is strongly recommended to read this article to the very end. The easiest way to solve the problem is to reinstall the operating system, which is very likely to help. But the fact is that on the new platform you can also meet the fact that error 720 will not go anywhere when connecting to the Internet, so we'll leave it to the very end.

There was a code 720: a connection error, how to solve the problem?

Even a beginner can cope with this method. Here, from you, practically nothing is required. It is necessary to reset the settings to those that stood in the factory. To do this, click "Start", then "Run" and type cmd command. After that, the following phrase is entered: netsh int ip reset resetlog.txt. And we need to enter one more similar phrase: netsh winsock. The next stage is the restart of the personal computer. Try to connect to the Internet. Most likely, the error will disappear, but there is a high probability that most programs that require connection to the Internet will stop working. You will need to reinstall them. The whole point is that the commands you typed overwrite part of the registry. And now we go further.

Reinstalling the Network Card Driver

This is a little more complicated, so read it carefully, repeat it and it will work out. Again, we will need to rewrite the registry a little, only this time in a different way. Go to the "Start", "Run", enter the command regedit. We completely remove the partitions, which somehow relate to wincock. We need to erase the records: HKEY_LOCAL ... wincock and HKEY_LOCAL ... wincock 2. We reboot the computer and try to connect to the network. Note: Everything that you deleted will be automatically restored by the system, so you can not worry about it again. If everything turned out, then you will not see the inscription: "Error 720". Windows 7, 8 may require changing the file nettcpip.inf.

"Error 720": "MTS" -modem and "Beeline"

As practice shows, quite often such a problem occurs on the above devices. It should be noted that the error can be corrected in exactly the same way as for a conventional modem. Therefore, before applying for support, try the above actions. Finally, go to the Windows / inf folder. There, find the file nettcpip. Go into it and find the TCPIP string has properties and after the sign, write 0x80. Save the changes and close the file, and in the settings you can check the box "read only". After rebooting, you can delete and then reconnect the connection. To do this, go to the "Control Panel", "Network Connections" and select the "Add and Install" protocol. Use the previously edited document as the disc. Reboot the PC, "Error 720" "Megaphone" -modem should be solved.

We carry out diagnostics

In some cases, before you delete or reinstall anything, you need to perform a diagnosis that will accurately show what the problem is in exactly. Go to the "Start", then "Run", and afterwards in the field enter Command. After that it is necessary to write Netdiag. As a result, you can observe the results for several components of the network. Winsock will also be included here. To get the information we need, write the following: / v: Netdiag / test: winsock / v. If you did not receive any errors during the execution of the action, then everything is in order. If there are problems, you need to restore the corrupted configuration. How to do it, we already said. As you can see, the "720 error" of the PPPOE connection is solved, but for this it is necessary to make efforts. With a probability of 90%, your problem will be solved, but it is possible that you will have to reinstall the operating system.

What else to pay attention to?

As already noted above, there is a possibility that none of the above will help. In this case, you can recommend trying to remove and install the TCP / IP protocol. It is likely that this will fix the situation. In any case, the reinstallation of the operating system should be performed only after all the options have been tried and nothing has helped. But again, using a Windows license reduces the risk of "Error 720" to a minimum. Moreover, you can be sure that everything will work. The same applies to the modem. If it was set up by a professional and the OS is licensed, then with 100% probability you will not get such errors. Of course, at any moment you can look at the log file, which will tell you what the snag is, you can fill it in the forum where the experts gather, and there they will certainly find the optimal solution. The file name is PPP.log, it is stored% systemroot% / tracing.

Therefore, you can try everything, but in addition to reinstalling the operating system or elementary removal of the virus does not help.
