Using PowerShell to change the User Principal Name (UPN) for a user in Active Directory!
Dear Windows Active Directory friends, I am absolutely aware that there are probably already a lot of articles on this topic. Nevertheless, I would like to show you my steps how I did this in a small infrastructure. But why would I want to change the User Principal Name (UPN)? Let's say you want to synchronize the local Active Directory with the Azure Active Directory and you use in the local domain the DNS suffix e.g. tomrocks.local, then the accounts in Azure are created with the default DNS suffix e.g. yourcompany.onmicrosoft.com. In my case, I added a custom domain in Azure: tomrocks.ch. In order to create the accounts correctly in Azure, the first step is to adjust the UPN of the users in the local Active Directory. I use the PowerShell ISE for this, but of course you may also work with another editor. Please start with the following steps to begin the "journey" (the Hashtags are comments): #The first two lines have nothing to do with the configuration but make some space at the bottom of the ISE. Set-Location C:\ Clear-Host #Get a list of the UPN suffixes Get-ADForest | Format-List UPNSuffixes #Let’s add the UPN suffix Get-ADForest | Set-ADForest -UPNSuffixes @{add="tomrocks.ch"} #Get a list of the UPN suffixes Get-ADForest | Format-List UPNSuffixes #List of all the AD Users in the organization Get-ADUser -Filter * | Sort-Object Name | Format-Table Name, UserPrincipalName #Change the UPN for all the AD users in the organization $LocalUsers = Get-ADUser -Filter {UserPrincipalName -like '*tomrocks.local'} -Properties UserPrincipalName -ResultSetSize $null $LocalUsers | foreach {$newUpn = $_.UserPrincipalName.Replace("tomrocks.local","tomrocks.ch"); $_ | Set-ADUser -UserPrincipalName $newUpn} #Confirm that the UPN is changed Get-ADUser -Filter * | Sort-Object Name | Format-Table Name, UserPrincipalName I know this is nothing spectacular at all, but I wanted to share my findings and experiences with you. Thank you for your attention. Kind regards, Tom Wechsler P.S. All scripts (#PowerShell, Azure CLI, #Terraform, #ARM) that I use can be found on github! https://github.com/tomwechsler

Share & NTFS permissions export
Hi, I need to export a report from my file server for all the share & NTFS permissions to csv file. I found the next script: $FolderPath = dir -Directory -Path "#Requested Folder path" -Recurse -Force $Report = @() Foreach ($Folder in $FolderPath) { $Acl = Get-Acl -Path $Folder.FullName foreach ($Access in $acl.Access) { $Properties = [ordered]@{'FolderName'=$Folder.FullName;'AD Group or User'=$Access.IdentityReference;'Permissions'=$Access.FileSystemRights;'Inherited'=$Access.IsInherited} $Report += New-Object -TypeName PSObject -Property $Properties } } $Report | Export-Csv -path "#Report Export path" with this script, I got only the NTFS permissions. I need to combine also the share permissions to the same CSV file. thanks for the help.
CPU Load Percentage PowerShell Windows Server 2019
Hello friends I want to check the percentage of use of Windows Server 2019 Server processors. I tried to use the query I was doing with Windows Server 2012, but it returns me the empty value. Could anyone know how I can do this in Windows Server 2019?
