You should looking into this Group Policy setting under Computer Configuration:
Administrative Templates > Network > Offline Files > Allow or disallow use of the Offline Files feature There are other settings in there which might also help pass a PCI audit, such as Encrypt the Offline Files Cache. That setting could be used as an alternative in case you would like to keep the feature. *From:* [email protected] [mailto: [email protected]] *On Behalf Of *Richard McClary *Sent:* Tuesday, June 20, 2017 12:32 PM *To:* [email protected] *Subject:* [NTSysADM] PCI nightmare - c:\windows\csc files Greetings! Since MS had the annoying habit of enabling off-line caching, I have a PCI nightmare. All our workstations are Window 7 Professional, SP1. A scan by an application called “IdentityFinder” has located 3000+ files among several dozen machines it claims has either social security numbers or credit card information. They are off-line cached files in c:\windows\CSC\... So far, my Google searches seem to indicate I go to each machine (possibly remote desktop), log in, and delete off-line files (Sync Center, etc). This seems to delete my own off-line cached files on that machine (and there are none). I would prefer to do this remotely, also preferably accessing the C: drive on each machine without needing to log in (24x7 operation, and chances are most seats will be occupied). An aggravation is, I do not know where these machines are. They all have a 12-character “name”, and most differ from one another by 1 or 2 characters, which makes things extra fun. Trying to remotely access the C$ volume and taking ownership of the C:\Windows\CSC directory and whacking things has worked in the past (MS says to not do that – presumably because it damages the off-line caching system, which is just fine!), but there have been some machines where this has not worked. So to summarize, is there a way to remotely clean out the c:\windows\CSC folder on a number of remote workstations?
