I am trying to provide access to a user on mount point which is present inside D drive in Windows server. We are using Set-Acl command.
$Acl = Get-Acl "D:\MountPointName"
$Ar = New-Object System.Security.AccessControl.FileSystemAccessRule ("username", "FullControl","Allow")
$Acl.SetAccessRule($Ar)
Set-Acl "D:\MountPointName" $Acl
This is not working.

I am trying to change permissions on a file through Powershell, and am having trouble figuring out how to get this to work.
$path1 = "\\somepath1\somefile1"
$path2 = "\\somepath2\somefile2"
$acl = Get-Acl $path1
$access_rule = New-Object System.Security.AccessControl.FileSystemAccessRule("User","Write","ContainerInherit,ObjectInherit","None","Deny")
$acl.SetAccessRule($access_rule)
$acl | Set-Acl $path2
"User" is a specified usergroup, of many users, and is called something different in the actual code. This throws two errors:
Exception calling "SetAccessRule" with "1" argument(s): Some or all identity references could not be translated."
Set-Acl : Some or all identity references could not be translated.
Then, I try to dumb the code down, essentially trying to copy permissions of one file to another:
$path1 = "\\somepath1\somefile1"
$path2 = "\\somepath2\somefile2"
Get-Acl -Path $path1 | Set-Acl -Path $path2
Even this throws an error:
Set-Acl : Some or all identity references could not be translated.
If I understand these errors correctly, then my "User" is not being properly defined. I try to get the "User" info by running the Get-ADUser cmdlet, but the ActiveDirectory module must not be installed, because I receive this error:
Get-ADUser : The term 'Get-AdUser' is not recognized as the name of a cmdlet,.........
My main question now, is how can I get the user SID information to properly change the permissions on the file? Am I missing a step somewhere? Is there a better way to change file permissions? Can I even try to change permissions for a group? I have hit a wall trying to find a solution, lol.

I need to change a lot of sub folders's ACL rights. The folders all have the same name "06 - Offers". I've found a powershell command to "copy past" the acl rights from one folder to another. I wonder if anybody here can point me in the right direction to automate this?
It would need to search in a defined folder and change all the access rights for a specific folder in each of it's sub folders (if that makes sense).
(Get-Item 'C:\testfolder').GetAccessControl("Access") | Set-Acl -Path 'D:\realfolder'
So for example we have the folders:
D:\project\project1\06offers
D:\project\project2\06offers
d:\project\project3\06offers
etc...
And all the 06offers folders need the exact same ACL rights.
With this you should be able to create a solution which fits for you:
#Get "example" rights
$PathToExampleFolder = "PathToFile"
$MasterACL = (Get-Item $PathToExampleFolder).GetAccessControl("Access")
#Search all folders
$Folders = Get-ChildItem -Path "PathWhereTheFoldersAre" -Recurse -Filter "06offers"
#Set ACL
foreach ($folder in $Folders) {
Set-Acl -Path $folder.Fullname -AclObject $MasterACL
}
I was looking around to understand how to chmod (change permissions of a file) a file on Windows 7 Power Shell. So I have found different (wired for me, because I am used to simple chmod command) code snippets and wondering would't it be simple to wrap that wired commands in a chmod function and write it on in a $profile file of Power Shell. I guess this is what many ex-linux shell, but now power shell users would like to have for changing permissions of a file.
I am new to Power Shell. Please help me with the code.
Here is an example with the native way, using ACL and ACE. You have to build your own functions arround that.
# Get the Access Control List from the file
# Be careful $acl is more a security descriptor with more information than ACL
$acl = Get-Acl "c:\temp\test.txt"
# Show here how to refer to useful enumerate values (see MSDN)
$Right = [System.Security.AccessControl.FileSystemRights]::FullControl
$Control = [System.Security.AccessControl.AccessControlType]::Allow
# Build the Access Control Entry ACE
# Be careful you need to replace "everybody" by the user or group you want to add rights to
$ace = New-Object System.Security.AccessControl.FileSystemAccessRule ("everybody", $Right, $Control)
# Add ACE to ACL
$acl.AddAccessRule($ace)
# Put ACL to the file
Set-Acl "c:\temp\test.txt" $acl
(Get-Acl "c:\temp\test.txt").access
Read-Host "--------- Test Here --------------"
# Remove ACE from ACL
$acl.RemoveAccessRule($ace)
Set-Acl "c:\temp\test.txt" $acl
(Get-Acl "c:\temp\test.txt").access
Look at the following:
Set-Acl - Run Get-Help Set-Acl -Full
attrib.exe - Standard Windows tool for setting file attributes. Not Powershell-specific, but of course still works in Powershell.
icacls.exe - Standard Windows tool for setting ACLs. Not Powershell-specific, but of course still works in Powershell.

Just do a web search for chmod powershell.
I wanted to use WScript.Shell object to secure a registry path , e.g HKEY_LOCAL_MACHINE\SOFTWARE\Business Objects\Registration\UserProfile.
So the objective is that , create a new permission for 'everyone' , and deny the following: Delete , Create SubKeys etc.
Googled a lot , and didn't get a deal on my specific problem , could anyone give me a hint on this point ? Thanks !
maybe this can help
$acl = Get-Acl "HKLM:\SOFTWARE\Business Objects\Registration\UserProfile"
$rule = New-Object System.Security.AccessControl.RegistryAccessRule ("mycomp\everyone","FullControl","Allow") # or deny...
$acl.SetAccessRule($rule)
$acl |Set-Acl -Path "HKLM:\SOFTWARE\Business Objects\Registration\UserProfile"
To add or remove an access rule you need to create the rule as an object of type RegistryAccessRule, and then either create or remove the rule from the ACL with the SetAccessRule() or RemoveAccessRule() methods
Just for have another example: Set-ACL on registry key
I'm currently using Vista 32-bit. How do I add the Windows security group "Everyone" and give full control to a directory and all of it's sub-directories and all files? Is there a powershell script that I could use?
Thanks!
I've expanded on martona's snippet and was able to give access to all folders and sub-folders. Here's my code -
$FilesAndFolders = gci "c:\data" -recurse | % {$_.FullName}
foreach($FileAndFolder in $FilesAndFolders)
{
#using get-item instead because some of the folders have '[' or ']' character and Powershell throws exception trying to do a get-acl or set-acl on them.
$item = gi -literalpath $FileAndFolder
$acl = $item.GetAccessControl()
$permission = "Everyone","FullControl","Allow"
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
$acl.SetAccessRule($rule)
$item.SetAccessControl($acl)
}
Sometimes the "native" PowerShell way isn't necessarily the best way. For something like this I would still use icacls.exe. Remember that good ol' exes work pretty good in PowerShell. Just cd to the directory you want to set and execute:
icacls $pwd /grant "Everyone":(OI)(CI)F
This will give Everyone full access to the current directory downwards (via permission inheritance). This should work as long as there are no explicit denials to Everyone in the dir structure.
$acl = Get-Acl c:\mydir
$permission = "Everyone","FullControl","Allow"
$rule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
$acl.SetAccessRule($rule)
$acl | Set-Acl c:\mydir
