I've noticed from the Windows 7 32bit Event viewer numerous errors of the type:Event 1012, DNS Client Events. There was an error while attempting to read the local hosts file.
I have checked the normal location of the Hosts file and it's missing - there are only 4 files there: Imhosts.sam, networks, protocol and services.
I've Googled and found no solution that works, I've run SFC /SCANNOW and it although it found and repaired some corrupt files it hasn't cured the Hosts file issue.
My question is: Should I worry since the PC seems to be running OK?
