Unable to connect to windows system. Windows System Event Notification Service error. Windows cannot connect to the "Group Policy Client" service

Not often, of course, but sometimes users of Windows-based computer systems encounter an unpleasant situation. The system reports that Windows cannot connect to the service responsible for some process. Consider the most common types of errors and the corresponding methods for correcting them.

Windows cannot connect to the service: possible situations

It is believed that among all the errors that occur, the most significant failures to be corrected are the two main ones: the inability to start the system event notification service (second name - SENS) and to the system component responsible for installing software of any type in the system. It is easy to guess that in the second case we are talking about the Windows Installer service, although not only this component, but also other types of installers can be used as an installer.

In the first situation, the problem is that when the notification component is disabled, the system simply restricts the rights of a user who is not logged in under an Administrator account. Equally, this also applies to problems associated with the fact that the Windows Installer service is disabled. Hence the simplest conclusion: these components must either be enabled or restarted.

The simplest way to fix a crash

So, let's look at the simplest situation. If the user knows exactly at what point the failure occurred (before that everything worked fine), you can try to simply restore the system. Note that now we are not talking about the reasons that caused a failure or a change in settings due to a virus impact. Checking for threats is not discussed. The user himself must understand that this is a paramount task in terms of security.

To roll back the system, you should enter the "Recovery Backup Center", where you can use the appropriate section. In this case, if there is no checkpoint in the presented list, you need to expand the list through the line showing all available points (use another rollback point). We select the time preceding the appearance of the first message that Windows could not connect to the SENS or Installer service, and roll back the system (the reboot will occur automatically).

Troubleshooting System Event Notification Service

This problem is perhaps the most common. Both viruses and some programs installed on the system could disable Windows services, change their startup parameters or settings. We assume that there are no viruses in the system, and recovery does not help.

To fix this problem, you will have to do a complete reset of some settings of this system component, for which you will need to run the command prompt as Administrator. This is done by typing cmd in the Run console, a quick call is made using the Win + R keys. The following should be written on the command line:

route-f;
netsh winsock reset.

For fidelity, the above two commands are used, but in most cases only the second can be entered. After the commands work, you will need to reboot.

Issues with the Windows Installer Service

With the installer, the situation is somewhat more complicated. There can be two scenarios for the development of events: either the user does not have administrator rights, or the service is simply disabled.

For the first situation, the most logical solution would be to log in under an admin account or assign administrator rights to the current account. However, this solution may not work either, and the system will again report that Windows cannot connect to the installer service. It only says that the component itself is in an inactive state.

Troubleshoot installer issues

Now let's see how to start the Windows Installer service (the solution is applicable for all services and problems with their disabled state). In this case, although we are talking about a specific component, understanding this issue can be useful in the future when correcting other errors.

You can also access the section for managing these components in the Run menu by typing the services.msc command in the console line. You can also enter this section through the computer management menu.

After entering, we look at the right side of the editor, where local Windows services are located. Here you need to find the line with the name of the component you are looking for (in our case, this is the Windows installer) and look at the set startup type. The value must be set to a manual type. If it differs (usually set to automatic), double-click to open an additional settings window. On the corresponding tab, select the desired value from the drop-down list, and then save the changes made. In principle, in most cases it is not necessary to restart the device, but to be sure, it is better to perform a full restart and then see how the system will behave.

One could also try to change similar settings in the system registry, which, in general, duplicates the parameters set in this section. But this method is more time-consuming and time-consuming, and in the absence of special knowledge, it is better not to go into the registry without the need.

Correcting errors with an automated utility

Finally, if the troubleshooting steps above don't work, which happens quite often too, and the notification that Windows can't connect to service such and such appears again and again, you can use the automated fixes offered for download and install from the official Microsoft support page.

In this case, we are talking about a small program called Microsoft Fix It. Another method to fix the problem can be to download the installer's installation distribution kit from the same resource and then integrate it into the system. True, it should be done exclusively by the administrator, perhaps even through the command line.

Conclusion

Finally, it is worth noting that only the two most common situations and the simplest methods for eliminating problems that have arisen have been considered here. In some cases, when using the command line to reset the parameters, the commands used can be much larger, and after executing them, you will still have to delve into the network settings. Such a solution was not considered only because it is much more complicated and simply will not be useful to most users. In the simplest version, one team is enough, a maximum of two. Additionally, it would be possible to check the integrity of system components through the sfc /scannow command, but, as practice shows, it is used, so to speak, just in case.

By the way, for some reason, according to statistics, such problems most often appear in the version of Windows Vista, which is already criticized for the fact that even with updates being installed, it still remains unfinished and “raw”.

This is how a laptop (netbook, etc.) with a Wi-Fi network seems to work and no questions. And one day you turn it on - and an error occurs: "Windows could not connect to Wi-Fi ...". What to do?

So actually it was with my home laptop. In this article I want to tell you how you can fix this error (besides, as practice shows, this error is quite common).

The most common causes:

1. Lack of drivers.

2. The router settings have gone wrong (or changed).

3. Antivirus programs and firewalls.

4. Conflict of programs and drivers.

And now about how to eliminate them.

How to fix "Windows could not connect to Wi-Fi network" error

1) Setting up Windows OS (for example, Windows 7, in Windows 8 - similarly).

If you still get an error stating that it is not possible to connect to the network (as in the picture below), click on the " troubleshooting"(I know that many are very skeptical of her (I myself treated the same until she helped restore the network a couple of times)).

If the diagnostics did not help, go to " Network and Sharing Center» (to enter this section, just right-click on the network icon next to the clock).

Now we just delete our wireless network, to which Windows cannot connect in any way (by the way, you will have your own network name, in my case it is “Autoto”).

Again we try to connect to the Wi-Fi network that we removed in the previous step.

In my case, Windows was able to connect to the network without any questions. The reason turned out to be banal: one "comrade" changed the password in the router settings, and in Windows in the network connection settings, the old password was saved ...

2) Setting up a Wi-Fi network in the router

After checking the wireless settings in Windows, the second thing to do is to check the router settings. In 50% of cases, it is they who are to blame: either they went astray (which could happen, for example, during a power outage), or someone changed them ...

Because you couldn’t connect to the Wi-Fi network from a laptop, then you need to set up a Wi-Fi connection from a computer that is connected to the router using a cable (twisted pair cable).

In order not to repeat myself, here is a good article about. If you can't log in, I recommend that you read this:

In the router settings we are interested in the “Wireless” section (if in Russian, then setting the Wi-Fi parameters).

For example, in TP-link routers, this section looks something like this:

Setting up a TP-link router.

By the way, in some cases it may be necessary to reset the router (router). On its body there is a special button for this. Hold it down and hold for 10-15 seconds.

Task: change the password and try to set up a wireless connection in Windows (see point 1 of this article).

3) Update drivers

The absence of drivers (however, as well as installing drivers that are not suitable for the equipment) can cause much more serious errors and failures. Therefore, after checking the settings of the router and the network connection in Windows, you need to check the drivers for the network adapter.

How to do it?

4) Configuring startup and disabling antiviruses

Antiviruses and firewalls (with certain settings) can block all network connections, supposedly protecting you from dangerous threats. Therefore, the easiest option is to simply disable or delete them for the duration of the setup.

About autoload: for the time of setup, it is also desirable to remove all programs that are automatically loaded with Windows. To do this, press the combination of buttons " Win + R" (valid in Windows 7/8).

Then enter the command in the "open" line: msconfig

5) If all else fails...

If Windows still cannot connect to the Wi-Fi network, you can try opening the command prompt and entering the following commands in sequence (enter the first command - press Enter, then the second and Enter again, etc.):

route -f
ipconfig /flushdns
netsh int ip reset
netsh int ipv4 reset
netsh int tcp reset
netsh winsock reset

Thus, we will reset the parameters of the network adapter, routes, clear DNS and Winsock. After that, you need to restart the computer and reconfigure the network connection settings.

If you have something to add - I will be very grateful. Best wishes!

The error "Failed to connect to the windows service" can occur for various reasons. The System Event Notification Service, Group Policy Client, may stop working. It is also very common to see this message on the weather gadget in windows 7. The consequences of such unsuccessful connections are different, but almost always lead to system inoperability.

Many users have a problem when the tray starts showing the message "windows cannot connect to the 'System Event Notification Service' service". This prevents regular users from logging in."

At the same time, the computer starts to load slowly or does not load at all, freezes, a black screen appears when logging in, programs start and open very slowly, while the CPU shows 100% load, but does not load anything specific. Also, windows restore may not work. In general, it becomes completely impossible to work on a computer.

In most cases, these problems occur due to corrupt registry keys with Winsock settings for various reasons. It can be damaged due to incorrectly installed software, viruses, incorrect settings, and incorrectly installed updates. There may be other reasons as well.

How to fix system event notification service error

The first thing you can do is try to roll back the system to a previous state. To do this, go to Start, open the Control Panel, select System and Security - System Restore.

Select the restore point that appeared before the start of an error about connecting to the windows service, and start the process. But in some cases, this may not work due to system problems or missing restore points. Be sure to check the system with antivirus and garbage cleaner. This can help.

If the problem remains, then we open the command line and write: “route -f”, press Enter, on the next line we write “netsh winsock reset”. Close and restart the computer.

If it doesn’t help, open the command prompt again and enter the following commands in sequence:

ipconfig /flushdns
nbtstat -R
nbtstat -RR
netsh int reset all
netsh int ip reset
netsh winsock reset
netsh interface tcp set global autotuninglevel=disabled

And reboot again.

You can also try opening the Network and Sharing Center and clicking on "Change adapter settings". Next, right-click on "Local Area Connection" and select Properties. Opposite the “Client for Microsoft Networks” there should be a checkmark, if it is not there, put it on and reboot again.

If, nevertheless, such a problem has not disappeared, then you will have to reinstall the system.

Service on gadgets does not connect

Everyone's favorite gadgets appeared in windows 7, but Microsoft stopped supporting them and one day instead of the usual gadget, for example, the weather, a message will be displayed that it was not possible to connect to the service.

In some cases, simply restarting the application helps, but over time it may stop working altogether. To do this, click on the cross in the corner, then right-click on any free space on the desktop and select Gadgets, then drag "Weather to the desktop". Also, to solve problems, you can change the city to another and then return the current location again.

You can try to revive the weather gadget. First you need to close the application (click on the cross in the corner of the gadget). Next, go to My Computer, open drive C, select the "Users" folder, click on the folder with the username in it and open it in sequence: AppData-Local-Microsoft-windows Live-Services-Cache.

The AppData folder may not be visible. To make it visible in windows 7, press Ctrl + C and select "Tools" in the top menu that appears. Next, select the "Folder Options" tab and select "Show hidden files and folders". In windows 8, this can be done in the top menu by selecting the View tab. This should fix the error issue.

windows can't connect to the "Group Policy Client" service

You may receive a Group Policy Client connection error when loading. This may prevent users other than the administrator from logging in. And if there are several computers connected to one network, then this problem can interfere very much. There may be other consequences as well.

First, you can try to enable the service manually. To do this, go to the control panel, select System and Security, then Administrative Tools and Services. Locate the Group Policy Client, right-click and select Enable. But this method doesn't always work.

You can try to roll back the system to an earlier state. Also check if all updates are installed.

The problem may disappear when you reboot, but it will not go away from this.

To fix the problem, you can try the following:

go to windows under the Administrator account and call the line run Win + R - in it we write regedit.exe;
the registry editor will appear in it, sequentially open the folders HKEY_LOCAL_MACHINE-SOFTWARE-Microsoft-windows NT-CurrentVersion-Svchost;
create a GPSvcGroup section in it (right mouse button);
in the GPSvcGroup section, create two more parameters:
DWORD (32 bits) name AuthenticationCapabilities value 0x00003020 (12320) DWORD (32 bits) name CoInitializeSecurityParam value 0x00000001 (1)
We reboot.

The most extreme method of fixing the error is to reinstall the system.

Computer help

It happens that a computer or laptop works, it works, and then one day, when turned on, something in it switches over and it gives an error: "". Sadness, especially if the one who "cleans the computer" is far, far away, or even completely absent. But, if the text of the error contains the words “System event notification service”, but below I will show how to fix it myself. ;)

A bit of theory. For those who are bored - the solution is at the end;)

System event notification service

System Event Notification Service - Monitors system events and notifies subscribers of the COM+ event system of these events. So it is written in the description of this service in Windows 7. We will not get deeper. We need to "fix" the computer, not become a system administrator.

What is going on?

As soon as the computer is ready to give an error: "", it loads Windows in a strange way. And everything becomes gray, boring and depressing. This is what prevents you from continuing to hang quietly on VKontakte, Odnoklassniki or on some video sites. =)

And it looks like this. The line with the button Start” becomes like a broken one:

And another error pops up:

And they write terribly incomprehensible things:

Windows cannot connect to the System Event Notification Service. This prevents regular users from logging in.
An administrator user can view the system event log to determine the cause of the problem.

How to fix your computer with this error

So what to do?

1. Open the command line (console) with administrator rights in Windows.

2. Enter the command route -f and press Enter

This command requires administrator rights.

What does the route -f command do?

Clears the routing table of all entries that are not host routes (routes with a subnet mask of 255.255.255.255), a network loopback route (routes with an endpoint of 127.0.0.0 and a subnet mask of 255.0. dot 224.0.0.0 and subnet mask 240.0.0.0).

3. Enter the command netsh winsock reset and press Enter

After running this command, Windows will prompt you to restart your computer.

What does the netsh winsock reset command do?

Winsock stands for Windows Sockets. This is a key mechanism in the Windows networking subsystem, and allows applications to access the network quite easily without the need for low-level networking. So, Winsock is a modular thing, and handlers for a variety of protocols and network interfaces can be built into it. In particular, antiviruses are built into it, intercepting and scanning network traffic. And no one is stopping the virus from getting in there too. The trick is that such a handler must be serviceable and must ensure that the packet is skipped. If the handler is damaged and does not ensure the transfer of the packet further along the chain of handlers, then the user will receive a broken Internet, which can be cured by resetting the Winsock stack to the default state, which is what the netsh winsock reset command does.

4. Restart your computer or laptop

How to "heal" a computer even faster (in the style of VZHUH)

If this mistake is repeated regularly, then again it will be long and tedious to look for that instruction. Therefore, I advise you to create a bat file and place it in a place where you can always find it.

Instructions for creating a "healing" bat-file:

1. How to create a bat file (batch file) ← this is a link to the article for those who want to understand how to do it

The contents of the bat file should be like this:

Route -f netsh winsock reset

2. How to run a bat file (batch file) with Windows administrator privileges ← this is a link to an article for those who want to figure out how to do it

3. Running a batch file is much faster than using the command line. I recommend;)

Well, if something remains unclear, ask and share useful information with friends, friends and parents. ;)
