How do I fix Windows 7 taking ages to logon and shutdown, login network connectivity?

Hi there,

I have the following setup:

MDT Server 2012
Windows 7 SP1 32 Image
Works perfectly on the following models
HP 6470
HP 6475
Lenovo M72e
Lenovo M73e

HP 640 G1

Getting following error after imaging:

“Windows could not connect to the System Event Notification Service . Please consult your system administrator”.
Logging on and Shutdown taking forever.
Losing Network connectivity

Tried the following:

KB Article Number(s): 2590550
Language: All (Global)
Platform: i386
Location: ( -Not applicable

Installed this driver:


Did the following:

•      Boot the computer in safe mode windows 7
Default GUI screen will be displayed
Click on Start button.
Type Cmd in the Start Search text box.
Right click on cmd.exe and Run Command Prompt as an Administrator. Allow elevation request.
Type netsh winsock reset in the Command Prompt shell, and then press the Enter key.
Restart the computer

Deleted all the log files in C:\Windows\Sysytem32\Winevet\Logs

Still no joy!!!

COM+ Event System service must also be running for System Event Notification Service to work.  Look at that.  You may need to be Administrator to do that.

Have you looked into Event Viewer to see if any errors at logon and logoff are reported?  Slow logon often means too many programs are trying to start at boot.  Try a Clean Boot.  If that helps, that confirms that a start up program is at least partially to blame. Slow logoff often means some program is hanging up.  Use Process Explore to try to determine.  Are you using Forefront?

How are you connected to the network?

I would first check if the DNS is proper.
Then check for the time on the system and the server.
After which check the network connectivity between the system and the server.
Check for the hardware.

Is this happening for all the systems or only one system?

Do you see anything in the server logs when the system tries to login?

Hi there,

All services are running.
I have done a clean boot.
Ran Windows Repair
No anti-virus installed.

Even before machine joins a domain getting the errors. Happening on all HP 640 G1 models.

Hi All,

I have solved this myself my downloading the correct display drivers from AMD instead of HP. Seems it is a known issue for HP 640 G1 models!!!

Nobody came back with any answer and unfortunately this seems to be a recent trend with Experts Exchange and will make me think of renewing my subscription next year, as this has happened with my last couple of questions.
