Windows could not connect to the System Event Notification Service service.

Every so often, 1 in 50, my laptop is very slow to start-up I get the "Please Wait" before the login screen.  Once I do log in I get the error:  

"Failed to connect to a windows service.

Windows could not connect to the System Event Notification Service service. This problem prevents limited users from logging on to the system. As an administrative user, you can review the System Event Log for details about why the service didn't respond."

Aero seems to be disabled also and cannot be fixed without a restart.  This problem is getting to be bothersome and I need to know if it could be hardware related.  Thank you in advance for you help.

Hi,

Since when are you facing this issue?

Did you make any software or hardware changes to the computer recently?

Check if the System Event Notification Service is running or not. To check for the services

1.      Click on Start

2.      In the start Search box type Services

3.      Right Click on - RUN AS ADMIN

Check if the below mentioned services has the mentioned status and start up type.

System Event Notification Service            Started                 Automatic

Also, check the dependency services that are required for System Restore Service to run.

To check that double click on the service and click on the dependency tab.

For the system being slow you may try to improve the performance by optimizing Windows and check if that helps. Follow the link given below on how to optimize Windows.

The aero issue can be resolved by installing or reinstalling the updated graphics card drivers. You may check if any update for the Graphics card is available for your computer from the computer manufacturer.

    This problem just popped up for me. Took forever to boot up and the desktop is in classic mode. I tried resetting Winsock which worked for one reboot and then the problem came back. I reinstalled Windows 7 which worked for one reboot. Then I read something about audio drivers or other drivers possibly being the problem which didn't make sense to me since my drivers were all up to date.

    But here is how I fixed it. I did a clean boot using msconfig. I left all of the microsoft services on and disabled everything else. Reboot. The problem was gone. Everything back to normal. So then I decided to try and find out which service was causing the problem so I did another clean boot but this time I enabled my audio driver. And that was it.

    PROBLEM SOLVED. For me anyway. Here's the short version

    -Go to start

    -type msconfig and open

    -under General check Selective startup

    -uncheck load startup items

    -under services tab check Hide all Microsoft Services

    -Then click disable all

    -reboot

    at this point if it worked for you like it did for me you can go through the list of services enabling them and rebooting to figure out which one is messing up your computer. For me it was DTSAudioSvc.

    I had the same problem and for me it was also DTSAudioSvc that was causing the problem.  

    Did get any other problems when turning that service off?  

    Thanks 

    Martin
