I've never seen or had this happen before .

Went to check Event Viewer today and got an error message that "Event Log Service is Unavailable". Checked Windows Services and sure enough Event Log Service is stopped and won't start. When I try to start it, it gives this error message: "Error 1747:The authentication service is unknown."
I tried a System Restore, but for some reason it wouldn't complete, and no restore was done. (3 different restore points)

I Googled the error message and didn't really come up with anything pertinent.

Anybody have any insight on this issue?

Windows Vista Home Premium.

Thanks,

Paul
