Set User's Logon hours based on admin's requirement (PowerShell)

Introduction

This PowerShell Script shows how to set active directory user’s logon time.

Scenarios

Sometimes IT admins want to set the user account logon hours to restrict user logon time. This script can help to do it.

Script

Step1: Run the script in the Windows PowerShell Console, type the one command: Import-Module <Script Path> at the prompt.

For example, type Import-Module C:\Script\ SetADUserLogonTime.psm1

This is shown in the following figure.
 

Step 2: You can type the command Get-Help Set-OSCLogonHours -Full to display the entire help file for this function, such as the syntax, parameters, or examples.

Here are some code snippets for your reference.

#Assign logon binary value to 'Logonhours' attribute.
If($SamAccountName)
{
    Foreach($User in $SamAccountName)
    {
        Get-ADUser -Identity $User | Set-ADUser -Replace @{Logonhours = [Byte[]]$HourBinary}
        Write-Host "Successfully set user '$User' logon time."
    }
}
 
If($CsvFilePath)
{
    If(Test-Path -Path $CsvFilePath)
    {
        #import the csv file and store in a variable
        $Names = (Import-Csv -Path $CsvFilePath).SamAccountName
 
        Foreach($Name in $Names)
        {
            Get-ADUser -Identity $Name | Set-ADUser -Replace @{Logonhours = [Byte[]]$HourBinary}
            Write-Host "Successfully set user '$Name' logon time."
        }
    }
    Else
    {
        Write-Warning "Cannot find path '$CsvFilePath', because it does not exist."
    } 
}

#Assign logon binary value to 'Logonhours' attribute. 
If($SamAccountName) 
{ 
    Foreach($User in $SamAccountName) 
    { 
        Get-ADUser -Identity $User | Set-ADUser -Replace @{Logonhours = [Byte[]]$HourBinary} 
        Write-Host "Successfully set user '$User' logon time."}} 
  
If($CsvFilePath) 
{ 
    If(Test-Path -Path $CsvFilePath) 
    { 
        #import the csv file and store in a variable 
        $Names = (Import-Csv -Path $CsvFilePath).SamAccountName 
  
        Foreach($Name in $Names) 
        { 
            Get-ADUser -Identity $Name | Set-ADUser -Replace @{Logonhours = [Byte[]]$HourBinary} 
            Write-Host "Successfully set user '$Name' logon time."}} 
    Else 
    { 
        Write-Warning "Cannot find path '$CsvFilePath', because it does not exist."}}
