On 32bit vista the PC is unable to connect to the Internet. At boot time a balloon comes out of systray:

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.”

I tried to check the event viewer but was told:
“Event Log service is unavailable. Verify that the service is running.”

So I thought I’d start the service manually but received:
“Windows could not start the Windows Event Log service on Local computer.
Error 1747: The authentication service is unknown.”

So I tried to start IPsec but this time:
“Windows could not start the IPsec Policy Agent service on Local computer.
Error 10107: A system call that should never fail has failed.”

So perhaps System Restore could put me right, but no “No restore points have been created on your computer’s system disk”

So I looked in System Properties and found that automatic restore points are enabled for the system disk. I then booted of the installation DVD and attempted to repair a computer unable to start, but was told that the PC would start. I then wished I had XP where I could just do a repair install and all my problems would be solved.
