Join Azure VM into AD and install SCCM Client

Jeremias Kühnis

Enclosed a script to join the Azure machine into AD and install the SCCM client. This is useful if you want to populate a native Azure VM that was not installed with SCCM. To make the AD-join a service user was assigned in the script, certainly not the most beautiful variant but this can be encrypted by a compiled EXE. This can be done with the following tool: https://gallery.technet.microsoft.com/scriptcenter/PS2EXE-GUI-Convert-e7cb69d5

Of course, network access to the AD and SCCM server must be available.

Verify Citrx HostedMachineID with VmWare Hypervisor

Jeremias Kühnis

Sometimes the HostedMachineID of Citrix does not match that of VmWare. This is often the case when cloning or moving machines. In Citrix Studio you will see the Powerstate of this machines as unknow and you can’t do any VM actions like reboot in the console.

With this script snippet it can be checked. To do this the variable “Broker” must be adjusted in the Script and the PowerCli and CitrixModule (BrokerSnapIn) must be loaded. Furthermore, the connection to the vCenter must be initiated via “Connect-VIServer vCName“.

#25.09.2019by J.Kühnis - Verfiy HostedMachineID with VmWare ESXi Hypervisoer

$Broker = "Enter your BrokerName"
$Brokermachines = Get-BrokerMachine -AdminAddress $Broker | Select MachineName,DNSName,HostedMachineID

Foreach ($Machine in $Brokermachines){
    IF(get-vm $Machine.DnsName -ErrorAction SilentlyContinue){
        IF($Machine.HostedMachineID -eq (Get-View -id (get-vm $machine.DNSName).id).config.uuid){
            Write-Host $Machine.DnsName "HostedMachineID is matching" $Machine.HostedMachineId -ForegroundColor Green
        }Else{
            Write-host $Machine.DnsName "Mismatch ID: VmWare UUID =" (Get-View -id (get-vm $machine.DNSName).id).config.uuid "; Citrix HostedMachineID =" $Machine.HostedMachineID -ForegroundColor Yellow
        }

    }Else{
        Write-host $Machine.DnsName "MachineName not Found on ESXi" -ForegroundColor Yellow
    }
}

Now that the machines have been read out, the connections can be fixed.

vCenter Cert thumbprint update:

# Open an admin POSH console, load the Citrix Modules (asnp citrix*) and cd to XDHyp:/Connections and run ls. Check the SSLThumbprints entry.
asnp citrix*
cd XDHyp:/Connections
ls
Set-Item -LiteralPath "XDHyp:\Connections\vCenters Name" -sslthumbprint "123456789ABCD123456789ABCDE123456789ABCD" -hypervisorAddress https://vcenter-name/sdk

The letters in SSL-Thumbprint must be uppercase.

In this blog the problem is also discussed in detail:

Citrix Studio: Cannot connect to vCenter server due to certificate error

Get reserved Memory of ESXi Host

Jeremias Kühnis

With the command Get-VMHost you can read values ​​such as the current memory consumption or the total number memory of a host. But I didn’t find a way to read out the value of the allocated memory of the subobjects (the VMs).

Here is an example of how this can be done. The script outputs a list of all hosts. In the attribute “AllocatedVMMemoryGB” you can see how much memory has been over-provisioned or it shows how much memory you could still use.

#by J.Kühnis 20.08.2019

#Class
Class VMHost{
    [string]$Name
    [string]$ConnectionState
    [string]$PowerState
    [int]$NumCpu
    [int]$MemoryUsageGB
    [int]$AllocatedVMMemoryGB
    [int]$MemoryTotalGB
    [string]$ParentCluster
    [string]$Id
    [string]$ProcessorType
}

#Vars
$VmHostArray =@()

#MainScript
Foreach($server in Get-VMHost){
    $a = (($server | get-vm).MemoryGB | Measure-Object -sum).sum
    $server = Get-vmHost -name $server.name
    $a = ("{0:N0}" -f $server.MemoryTotalGB) - ("{0:N0}" -f $a);

    $vmhost = New-Object VMHost -Property @{Name=$server.name;ConnectionState=$server.ConnectionState;Powerstate=$server.ConnectionState;NumCpu=$server.NumCpu;MemoryUsageGB=$server.MemoryUsageGB;AllocatedVMMemoryGB=$a;MemoryTotalGB=$server.MemoryTotalGB;ParentCluster=$server.parent;ID=$server.Id;ProcessorType=$server.ProcessorType}
    
    $VmHostArray += $vmhost

    Clear-Variable -Name a,vmhost
}

Scriptblock to check PVS Connection

Jeremias Kühnis

On the fly, I found no way to check which PVS servers & service are online. This is especially important if I want to issue PVS commands from Remote / Orchestrated. Enclosed I have made a small script block to check this. It is certainly not the best way, but it works. One possibility would be to retrieve the status of the PVS-services, but it is unclear whether one can actually connect to the servers trough PVS commands.

#by JKU 09.08.2019
$error.clear()
$k.clear()
$PVSConnectionServers.clear()

$PVSConnectionServers = @("PVS-Server01", "PVS-Server02")

$k = 0
Foreach($PVS_Server in $PVSConnectionServers){
    Set-PvsConnection $PVS_Server
    if($Error -match $PVS_Server){
        #Check Next Server
        $k++
        IF($k -eq $PVSConnectionServers.Count){
            Write-Warning "ALL PVS Servers are not reachable, stop script! $PVSConnectionServers"
            Return
        }
    }Else{

Example WPF Datagrid with Combobox (Powershell Binding)

With WPF GUI elements, it can happen that you like to connect two detached elements with each other. A classic example are comboboxes within tables. You want to read the value of the combobox with the corresponding row. For this the binding of elements is necessary. Enclosed a small example, how you can accomplish this:

local & remote msu patchfile installation with Powershell / Windows Update Standalone Installer

Jeremias Kühnis

Windows Update Standalone Installer

The patch installation is done via wusa.exe.

The following print screen shows the parameters of the Windows Update Standalone Installer.

local installation

As far as I know, the patch cannot be installed with native powershell, means we have to address the wusa.exe in powershell. Of course Powershell is a nice way to automate the whole process.

In the following example, the patch is copied from a UNC share and installed locally.

$patchname = "kb13245.msu"

$patchsource = "\\some\unc\path\kb13245.msu"

Copy-Item $patchsource -Destination "$env:SystemDrive\Temp" -Force

wusa.exe "$env:SystemDrive\Temp\$patchname" /quiet

remote installation

I was not able to run wusa.exe remotely, any tests with workflows, Remotepowershell (Invoke-Command CMDLeet) failed. Even triggering a localy copied batch file caused problems. The wusa.exe process was executed with the correct parameters but aborted after a few seconds.
Even with an Invoke-Command and the parameter -Wait it didn’t work.

Probably it’s because you intervene in the system and perform an unauthorized action.

With the PSExec.exe it is possible to start the process remotely.

The principle is very simple, you have to copy the patch to the appropriate target computer. Then PSExec starts a remote process on the target computer and executes the wusa.exe with the corresponding parameters. The wusae.exe must point to the path where the patch was copied.

#16.05.2019 by JKU
$Hotfix = 'kb-12345.msu'
$HostName = 'F.Q.D.N'
$DestinationPath = "\\$Hostname\c$\Temp\"

Copy-Item C:\temp\$Hotfix -Destination $DestinationPath
#Start Process with PSExec.exe
& C:\Temp\PsExec.exe -accepteula -s  \\$HostName wusa C:\Temp\$Hotfix /quiet /norestart

And so you can distribute a patch for multiple computers with a simple iteration.

full remote automation

There are of course several ready-made scripts to install multiple patches on multiple computers. The script which I use in the company environment, I have inserted below. The code does not come from me, but from the following forum post: https://community.spiceworks.com/topic/2054098-silently-install-patches-remotely-and-reboot?page=1#entry-7246666

Map Share to free Driveletter

Jeremias Kühnis

With this code snippet a share can be mapped to the next free drive letter.

$share = "\\any\unc\path"
$PSProviderAlphabet = [char[]]([char]'C'..[char]'Z')
$UsedPSProvider = (get-psdrive).Name | Sort-Object
$FreePSProvider = $PSProviderAlphabet | ? {$UsedPSProvider -notcontains $_}

New-PSDrive -Name $FreePSProvider[0] -PSProvider "FileSystem" -Root $share

It is especially useful if you have to work with a driveletter in the code or if the share has to be mapped in the Scirpt and has to be removed at the end of the script.
