lsass.exe security errors

[Guest]

My security event log is filled with these errors.
Does anyone know why or how to fix it?

I only have Lsass.exe on disk which seems to be the correct Microsoft program.
Can't find any entries in registry.
Virus scanner doesn't find anything.
But still getting security events.
