![]() This nice simple command once modified with your path to search and the output file name will generate a list of all of the EFS encrypted files in that path. txt files which you can review at a later time. If you are an admin of a file server, you can run this centrally or if users have local files, you could configure this as a logon script for the users and output the results to a network share as. Luckily, there is a few switches in the cipher utility that can do all the heavy lifting for us. This is the part I was primarily concerned about as where would the files be exactly given I’ve never knowingly used EFS. This will disable the ability for users to use EFS. ![]() In the EFS Properties, set the File Encryption using Encrypting File System (EFS) option to Don’t allow. ![]() Once in the PKI node, right-click on the Encrypting File System folder in the navigation area on the left. In the GPMC, open the GPO that you plan to include the setting in and navigate to Computer Configuration > Security Settings > Public Key Policies. This is easily done with Group Policy and is a setting that could and possibly even should be included in a baseline GPO for clients and servers (the setting is a Computer Configuration setting) but don’t put it in the Default Domain Policy as modifying this with additional settings isn’t best practice. It was a nice idea but it was troubled and flawed in that it was enabled by default and users could self-encrypt files without IT having implemented the proper tools to allow them to recover the files when disaster struck.įirst and foremost, we want to prevent any new EFS encrypted files from appearing. I’ve never knowingly used EFS but the presence of a certificate for that purpose lead me to believe there may be some files out there so I started looking.ĮFS was a technology that appeared circa Windows XP to allow users to encrypt files before BitLocker was a thing. When I started looking at decommissioning the ADCS role, I noticed that an EFS certificate had been issued to my domain user account. We all know that unbinding ADDS and ADCS can be a bit of a bore which is why nobody in the age of virtualization should be installing ADDS and ADCS on a single server together but that’s by the by. This server was originally installed using Windows Server 2012 R2 Essentials and since, I have performed a Standard edition, edition upgrade on the machine which means that the host has ADDS, ADCS, NPS and some other roles installed as part of the original Essentials server installation. At home last week, I started doing some preparations for upgrading my home server from Windows Server 2012 R2 to Windows Server 2016.
