Vista - Windows Vista: "System Event Notification Service"?

Please Help !

My HP running Vista Home Basic suddenly gave me the following error message on startup: "Failed to connect to a Windows service: Could not connect to System Event Notification Service".
Among other things, this prevents me from connecting to my internet network, so I can't get on-line.
Rebooting did not help.

Following the google search I used an elevated command prompt (click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator) and typing "NETSH WINSOCK RESET ", then press the Enter key, and then restart the computer.

I still cannot access my internet network, instead of not connection now I get the message "unidentified network" and I still cannot go online although there I have some Mbs

It sais (I do not understand this text )
"What netsh winsock reset command does are it resets Winsock Catalog to a clean state or default configuration. It removes all Winsock LSP (Layered Service Providers) previously installed, including the potential malfunctioned LSP that causes loss of network packets transmission failure. So all previously-installed LSPs must be reinstalled. This command does not affect Winsock Name Space Provider entries."

Please help me with the next step in order to be able to go online from my computer.
Thank you!
