I maintain our companies SBS2011 server, and I have duplicate file reports emailed to me on a monthly basis. I've noticed an increasing build up of duplicated files in the following directories:
NT SERVICE\TrustedInstaller
BUILTIN\Administrators
S-1-5-21-253125893-3659723687-2658493243-1156
NT AUTHORITY\SYSTEM
What are these directories, and can any of these duplicate files be removed safely without causing any problems?
Thanks for any ideas/info!
