Set-WebApplicationProxyApplication

The Set-WebApplicationProxyApplication cmdlet modifies settings of a web application published through Web Application Proxy. Specify the web application to modify by using its ID. Note that the method of preauthentication cannot be changed. The cmdlet ensures that no other applications are already configured to use any specified ExternalURL or BackendServerURL.

Set-WebApplicationProxyApplication -ID 994A4543-7983-77A3-1E6D-1163E7419AC1 -ExternalUrl https://webapp.abc.com/

How to access a Nano Server

Because Nano Server does not support a local session, it must be accessed remotely.

IP Address of the Nano Server: 10.10.10.1
1. Start an elevated PowerShell ISE session.
2. Set the Trusted Host. This is a one-time setting for each remote machine. You’re basically telling your development machine to trust the remote Nano Server.
Set-Item WSMan:\LocalHost\Client\TrustedHosts “10.10.10.1”
3. Start the session.
Enter the following commands into the PowerShell ISE command line:
$ip = “10.10.10.1” 
$s = New-PSSession -ComputerName $ip -Credential ~\Administrator
Enter-PSSession -Session $s

Powershell, SCCM, System Center Configuration Manager

Hot to use PowerShell to manage System Center Configuration Manager

The easiest way is by launching the Configuration Manager console. In the upper left corner, there’s a blue rectangle. Click the white arrow in the blue rectangle, and choose Connect via Windows PowerShell.

cm

Now, you need to import the Configuration Manager module by using the Windows PowerShell Import-Module cmdlet. To import the Configuration Manager module, you will have to specify the path to the Configuration Manager module or change to the directory that contains the module. Here, we’re going to change to the module’s directory.

PS C:\>

PS C:\> CD ‘C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager’

PS C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager>

Then import the module;

Import-Module .\ConfigurationManager.psd1

To run the Configuration Manager cmdlets, you need to switch the path to the Configuration Manager site.

PS C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager>CD MSN

MSN – is my site code

PS MSN:\>

Confirm that the Configuration Manager module has been loaded by using the cmdlet below;

PS MSN:\> Get-CMSite

Powershell

Powershell special characters

When you are using Powershell, it really helps if you use special characters to write your own scripts or interpret someone else’s scripts. Some of them are really common and get used very often….

# Hash – Single line comment

 

#This script is for ....
#This variable is to ...

 

$ Dollar sign – is used to declare a variable

$ComputerName = "Server1"
$password = "p@sw0rd"

 

| Pipeline- Executes the left side and with  the output feeds to the right

 

Get-Process | Select -first 10

 

% Percentage – Short for “FOREACH”

 

% ($Server in $Servers) { Write-Host $_}

 

? Question Mark – Short for “Where”

 

Get-process | ? {$_.name -like 'win*' -and $_.status -eq 'Running'}

 

@ () – Declares an array

 

$Servers = @ ("server1", "server2", "server3")

 

@ {} – Declares an hash table

 

$servers = @{"server1" = "Dell";
             "server2" = "HP";
             "server3" = "Nutanix"}

$servers["server3"]
Nutanix

------------------------------------ OR

$params = @{};
$params['class'] = 'Win32_DiskDrive';
$params['filter'] = 'size=256052966400'; #find a drive which is 256GB in size
		  
Get-WmiObject @params
Get-WmiObject -Class 'Win32_DiskDrive' -Filter 'size=256052966400'

 

& Ampersand – Executes strings as commandlets

 

& "Get-Scheduledjob"

 

! Exclamation – Short for “not”

$serverName = $null;
if(!$serverName) { Write-Host '$a is null' }

 

:: Double colon – Reference static member of a class. The class name must be enclosed in square brackets.

[string]::Equals = ("Computers", "COMPUTERS")
False # this will compare these two strings and returns false
