Our main DC has been missing out on patches and recently saw there was an error with TrustedInstaller, error 2: Can't find file. I saw some articles about replacing the files (which might be corrupt) from another Win2008 R2 server). I was going to do that and then realized the entire c:\windows\servicing folder does not exist on this server and that the error have been there for a while.
So, anyone tried to replace the whole folder with positive results to fix the issue. I understand it is only WindowsUpdate but still would prefer to correct. I was thinking of copying over and trying to duplicate the folder permissions, then reboot to get it to work but concerned since we only discovered AFTER we decommissioned our secondary DC. Thanks for any input.
