There is no “-force” switch for Remove-ADUser?

Posted in Windows Powershell, Windows Server | 4 Comments | 1,626 views | 22/08/2009 10:28

Are you kidding? How can I use “Remove-ADUser” to delete an user from Active Directory if there is no “-force” switch? Simply, it is for blocking automation scripts. We have so many IIS users in Active Directory. What should we do? Should we hire a new guy to manage users? I quit to use Powershell v2 AD modules for a while.

Update: You can assign $false to confirm parameter:

Remove-ADUser "User1" -Confirm:$False

Creating Active Directory User with Powershell

Posted in Windows Powershell | No Comment | 1,259 views | 18/08/2009 12:55

I created this script to create active directory user with Powershell.

function Add-ADUser
{
param ($UserID, $HostID, $CustomerID, $FirstName, $LastName, $Password, $CustomerOU)
 
    $FQDN = (Get-ADInfo).FQDN
    $ADDomain = (Get-ADInfo).Domain
 
    $CheckCustomerOU = Check-CustomerOU -CustomerID "$CustomerID" -CustomerOU "$CustomerOU"
    $CheckHostingOU = Check-HostingOU -HostID "$HostID" -CustomerID "$CustomerID" -CustomerOU "$CustomerOU"
 
    $CustomerOU = [ADSI] "LDAP://OU=$HostID,OU=$CustomerID,$CustomerOU,$FQDN"
    $PrincipalName = $UserID + "@" + $ADDomain
    $AddADUser = $CustomerOU.Create("User","CN=$UserID")
    $AddADUser.Put("GivenName", "$FirstName")
    $AddADUser.Put("SN", "$LastName")
    $AddADUser.Put("Description", "$FirstName $LastName")
    $AddADUser.Put("sAMAccountName", "$UserID")
    $AddADUser.Put("userPrincipalName", "$PrincipalName")
    $AddADUser.Put("DisplayName", "$FirstName $LastName")
    $AddADUser.SetInfo()
    $AddADUser.SetPassword("$Password")
    $AddADUser.SetInfo()
    $AddADUser.Psbase.Invokeset("AccountDisabled", "False")
    $AddADUser.SetInfo()
    $AddADUser.Put("userAccountControl", "66080")
    $AddADUser.SetInfo()
 
    If(!$AddADUser)
    {
        Write-Host "An Error Occurred."
        $Status = "0"
        Return
    }
    $Status = "1"
}

Creating Active Directory OU with Powershell

Posted in Windows Powershell, Windows Server | No Comment | 942 views | 18/08/2009 11:53

This is my simple Powershell script to create organizational units with Powershell.

function Add-CustomerOU
{
param ($CustomerID, $CustomerOU)
 
    $CheckCustomerOU = Check-CustomerOU -CustomerID "$CustomerID" -CustomerOU "$CustomerOU"
 
    If($CheckCustomerOU.Status -eq "0")
    {
        $FQDN = (Get-ADInfo).FQDN
        $CustomerOU = [ADSI] "<a href="ldap://$CustomerOU,$FQDN">LDAP://$CustomerOU,$FQDN</a>"
        $CreateOU = $CustomerOU.Create("OrganizationalUnit", "OU=$CustomerID")
        $CreateOU.SetInfo()
        If(!$CreateOU)
        {
            Write-Host "An Error Occurred."
        }
    }
    Else
    {
        Write-Host "Organizational Unit already exist on the Server" | Out-Null
        $Status = "1"
    }
}

This script creates an organizational unit under another one using some arguments.

Checking Windows Service Status with Powershell

Posted in Windows Powershell, Windows Server | No Comment | 1,009 views | 17/08/2009 10:59

Today, I created a Powershell script to check a service status and if it is stopped, that starts it.

$Status = (Get-Service MEMTAS).Status
If ($Status -eq "Stopped")
{
Start-Service MEMTAS
}

Then add this to Cronjob and set it to run every 5 minutes. MEMTAS is a service name of Mail Enable.

Checking Active Directory OU with Powershell

Posted in Windows Powershell, Windows Server | No Comment | 869 views | 16/08/2009 20:28

This is my custom Powershell script to check OU in Active Directory.

function Check-CustomerOU
{
param ($CustomerID, $CustomerOU)
 
    $FQDN = (Get-ADInfo).FQDN
 
    $CustomerOU = [ADSI] "LDAP://OU=$CustomerID,$CustomerOU,$FQDN"
 
    If(!$CustomerOU)
    {
        Write-Host "No such Organizational Unit on the Server" | Out-Null
        $Status = "0"
    }
    Else
    {
        Write-Host "Organizational Unit exist on the Server" | Out-Null
        $Status = "1"
    }
 
    $Results = New-Object Psobject
    $Results | Add-Member Noteproperty Status $Status
    Write-Output $Results    
}

As you see, it is too easy to check an Active Directory OU with Powershell.

Checking Active Directory User with Powershell

Posted in Windows Powershell, Windows Server | 1 Comment | 727 views | 16/08/2009 20:16

I needed to check an user from Active Directory with Powershell so I wrote this.

function Check-ADUser
{
param ($UserID)
 
    $Searcher = New-Object DirectoryServices.DirectorySearcher([ADSI]"")
    $Searcher.Filter = "(&(objectClass=user)(sAMAccountName= $UserID))"
    $CheckADUser = ($Searcher.Findall()).Count
 
    If($CheckADUser -eq "0")
    {
        Write-Host "No such user on the Server" | Out-Null
        $Status = "0"
    }
    Else
    {
        Write-Host "User exist on the Server" | Out-Null
        $Status = "1"
    }
 
    $Results = New-Object Psobject
    $Results | Add-Member Noteproperty Status $Status
    Write-Output $Results    
}

Usage Sample:

$Status = (Check-ADUser -UserID ysfozy).Status

This script can search user from Active Directory and show you results.
