Set Allow Log On Locally User Rights via Powershell, C# and CMD

Configure Allow log on locally user rights via Local Security Policy GUI

Follow the below steps to set Allow log on locally user rights via Local Security Policy

1. Open the Run window by pressing ‘Windows’ + ‘R’  keys.
2. Type the command secpol.msc in the text box and click OK.

3. Now the Local Security Policy window will be open, in that window navigate to the node User Rights Assignment (Security Settings -> Local Polices ->User Rights Assignment). In right side pane, search and select the policy Allow log on locally.

4. Double-click on the policy Allow log on locally, in the opened window click the button Add User or Group, select the user account you want to set Allow log on locally rights and click OK, and click Apply button to finish.

Set or Grant Allow log on locally user rights via Powershell

 We can set the Allow log on locally user rights using Powershell by importing the third party DLL ( Carbon ). Before you run the below script you need to the download latest Carbon files from here Download Carbon DLL.

Steps to follow to set Allow log on locally user rights via Powershell :

  1. Download latest Carbon files from here Download Carbon DLL.
  2. If you have downloaded the files, extract the zip file and you could see the Carbon DLL inside bin folder (In my case: C:UsersAdministratorDownloadsCarbonbinCarbon.dll).
  3. Copy the below Powershell script commands and place it notepad or textfile.
  4. Now you can replace your Carbon DLL path in following script for the variable $CarbonDllPath
  5. You can also replace the user identity that you are going to set log on locally user rights in the variable $Identity
  6. Now run as Powershell window with Admin Privilege (Run as Administrator)
  7. Copy the edited Powershell script and Run it in Powershell to configure Allow log on locally user rights.

$Identity = "DomainNameSvc_User_account"
$privilege = "SeInteractiveLogonRight"

$CarbonDllPath = "C:\UsersAdministratorDownloadsCarbonbinCarbon.dll"

[Reflection.Assembly]::LoadFile($CarbonDllPath)

[Carbon.Lsa]::GrantPrivileges( $Identity , $privilege )

Powershell output:

Set Allow log on locally user right via Command Line tool

You can use the NTRights.exe utility to grant or deny user rights to users and groups from a command line or a batch file. The NTRights.exe utility is included in the Windows NT Server 4.0 Resource Kit Supplement 3. Use the below command to set log on locally user right using cmd.

Refer: http://support.microsoft.com/kb/266280

Set Log on Locally user right

ntrights +r SeInteractiveLogonRight -u "DomainSvc_Test_user"

Revoke Log on Locally user right

ntrights -r SeInteractiveLogonRight -u "DomainSvc_Test_user"

Set or Grant Allo Log on locally right/permission to user using C#

You can use the below function GrantLogonLocallyRights to set log on locally rights to user using C# code. This function uses the class LsaWrapper.

static void GrantLogonLocallyRights(string userName)
{
    try
    {
        LsaWrapper lsaUtility = new LsaWrapper();

        lsaUtility.SetRight(userName, "SeInteractiveLogonRight");

        Console.WriteLine("Logon as batch job right is granted successfully to " + userName);
    }            
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
}
