Application log errors!

SINGLE DOMAIN.. 5 sites..5 DCs
Event viewer..application logs.. I get 2 errors every 5 minutes. SceCli (id 1202) and Userinv (Id 1000). I have checked microsoft and think I have it pinned down to policies in my sysvol folder (missing groups etc). In %SystemRoot%\Sysvol\Sysvol\DomainName\.. I have a folder Policies. These seems OK.
I also have 10 folders called Policies_NTFRS_(numbers) and 10 folders called Scripts-(numbers)

I don’t use NFS. Can I just delete these extra 10?
or how do I “clean up” to start fresh?
Thanks
