It only takes a minute to sign up. I'm trying to reset permissions on user directories and having a bit of trouble with the last step of my script. My script basically takes ownership of the entire user directory, resets the permissions on all files and folders for the directory, explicitly grants the permissions I need, stops all inheritance of permissions from parent folders, sets the rightful owner specified user for all files and folders, and then removes the permission I gave to myself so that I could operate on the files.

Does anyone know of any other way to accomplish this? An observation first: Every time you block inheritance you're cutting yourself off from future flexibility. I avoid blocking inheritance at all costs. The last permission doesn't inherit down into the subfolders. At each subfolder, inheritance remains enabled and you simply specify the user with "Modify" or "Full Control" rights depending on how you feel about users being able to set permissions inside their home directory.

Typically I set that last permission by adding "Authenticated Users" in the non-"Advanced" Security properties sheet, unchecking the "Read" and "Read and Execute" check boxes. That's about the easiest way, in terms of number of clicks, to set it. This is my SOP for user home directories, redirected "My Documents", "Desktop", etc folders, and for roaming user profile directories.

It works great. It's easier to solve a certain class of user problems if you can get to their files. It's a pain to "take ownership" and can be quite slow if there are a large number of files present, too. Obviously, EFS isn't the only show in town. Encryption is the real answer to solving the "limit the network Administrator's access" problem no matter how you slice it.

Icalcs is the replacement for cacls Change Access Control Listsa command-line utility that allows you to show and perform some operations on ACL for files or directories. ACL Access Control List is a list of permissions for a filesystem object and defines how its security is controlled by managing who and how it can be accessed. Actually, operations on ACL are not the only ones possible with this tool. What makes it a powerful tool is also the ability to perform backup and restore operations on ACL for files or directories, or to search for files that have a specific user as owner.

And in addition, in the event that an ACL is damaged or destroyed, with icacls you can restore it by resetting it and setting default permissions or inheriting those of the parent. Imagine that we have an external hard disk on which a study made in was stored, and we want to recover it, but we do not have complete control. One solution is, therefore, to use the reset function of Icalcs. But pay attention to the following steps. We must therefore first become the owner of the folder with the takeown command:.

A very simple operation from a point of view: information about the ACLs are saved in a file that can be used in case of need to restore a previous situation.

However, it should be noted that data on access rights, especially in shared folders, can be very variable over time. We could then find ourselves in a situation where we are going to restore a situation that is different from reality or even inconsistent. Moreover, the file that is created, openable and readable with a common text editor, seems to be a Unicode text. As you can see, in restore command case we will not use filediprova.

In Windows systems, the ability managing access control lists is a strength that allows users and processes to make the best use of resources.
