Can a user read data if they have NTFS Write and not NTFS Read?

In class we had some confusion between some NTFS permissions. Here is the official word from Microsoft on the ones in question.

Modify - Users can view and modify files and file properties, including deleting and adding files to a directory or file properties to a file.

Write - Users can write to a file.

Read & Execute - Users can run executable files, including scripts.

Read - Users can view files and file properties.

After testing this, yes the user with only Write access to the folder and its files can also read them.

Another part of this question is what happens to a high level permission when you explicitly remove some of the lower level permissions.

With the Modify permission set, you are also given Read & Execute, List folder contents, Read, and Write. By removing Read permission, you also lose Modify and Read & Execute. If you remove Write you only lose Modify.

Pay close attention to what rights you are giving, and removing from your users.

With the AD Recycle Bin Turned on, What Happens when you Create a User Account with a Password that does not meet the Password Policy?

This was an interesting observation from one of my Windows Server 2012 classes. While working with the AD Recycle bin in a lab, one of my students discovered some interesting accounts that were created. When he created user accounts that did not meet password complexity requirements, an account is temporarily made and then deleted. When a new password is provided that meets the password requirements, then a new account is made. We discovered this in two places. First off in the Active Directory Administrative Center. This is what caused the initial confusion. Take a look. This is in the Deleted Objects OU. You can see multiple deleted accounts for Test2 and one for Test3. Test3 is a valid, functioning user account. Using the PowerShell command Get-ADObject –IncludeDeletedObjects –Filter * –Properties ObjectSID we can see that indeed, two accounts were created, with one of them deleted. Notice the RID portion of the SID is different. ...

How to run GPResult on a remote client with PowerShell

In the past, to run the GPResult command, you would need to either physically visit this client, have the user do it, or use and RDP connection. In all cases, this will disrupt the user. First, you need PowerShell remoting enabled on the target machine. You can do this via Group Policy . Open PowerShell and type this command. Invoke-Command –ScriptBlock {GPResult /r} –ComputerName <ComputerName> Replace <ComputerName> with the name of the target. Remember, the target needs to be online and accessible to you.

Sticky Key problem between Windows Server 2012 and LogMeIn

This week I instructed my first class using Windows Server 2012 accessed via LogMeIn and discovered a Sticky Key problem every time you press the Shift key. Here is my solution to resolve this. First off, in the Preferences of LogMeIn for the connection to the Windows Server, click General . Change the Keyboard and mouse priority to Host side user and click Apply at the bottom. On the Windows 2012 server, open the Control Panel – Ease of Access – Change how your keyboard works . Uncheck Turn on Sticky Keys . Click Set up Sticky Keys . Uncheck Turn on Sticky Keys when SHIFT is pressed five times . Click OK twice. If you are using Windows Server 2012 as a Hyper-V host, you will need to redo the Easy of Use settings on each guest operating system in order to avoid the Sticky Key Problem. Updated Information: March 20, 2013 If you continue to have problems, Uncheck Turn on Filter Keys .
