I have been using Windows Server 2012 for quite some time & 1 of the best features in Management & Automation using PowerShell Web Access.
So What is PowerShell Web Access??
Examples of client devices include laptops, non-work personal computers, borrowed computers, tablet computers, web kiosks, computers that are not running a Windows-based operating system, and cell phone browsers. IT Pros can perform critical management tasks on remote Windows-based servers from devices that have access to an Internet connection and a web browser.
After successful gateway setup and configuration, users can access a Windows PowerShell console by using a web browser. When users open the secured Windows PowerShell Web Access website, they can run a web-based Windows PowerShell console after successful authentication.
Windows PowerShell Web Access setup and configuration is a three-step process:
You can refer Microsoft TechNet Library to get detailed step by step article http://technet.microsoft.com/en-us/library/hh831611.aspx
In today’s blog post I will show you how can you deploy PowerShell Web Access in test environment. I will be using both GUI method i.e. Server Manager & PowerShell based scripts. So let’s get started.
My Test Environment.
I am using 2 virtual machines. Windows Server 2012 Domain Controller & Windows 8 Client machine.
DPE-WS12-VM01 - Windows Server 2012 Datacenter – Domain Controller, PowerShell Web Access Gateway & Destination. DPE-WIN8-CLI01 - Windows 8 Enterprise – Domain joined client/workstation
Note: This is a test environment using Virtual Machines & leveraging sample self-signed test certificate.
Ideally, this is how the overall architecture would look like in production environment.
Step 1: Login to the Domain Controller machine DPE-WS12-VM01 to install PowerShell Web Access using Server Manager. WE WILL PERFORM THE STEPS USING SERVER MANAGER. Note: You can perform this Step 1 using PowerShell as well. Refer http://technet.microsoft.com/en-us/library/hh831611.aspx
In Step 1, we have installed the features Windows PowerShell Web Access & server role Web Server Role (IIS).
Step 2: Now that we have installed the feature Windows PowerShell Web Access, we will now need to configure PowerShell Web Access Gateway so that my Application Pool should be available in my IIS Manager under Default Website. WE WILL PERFORM THE FOLLOWING USING POWERSHELL.
When you install the feature Windows PowerShell Web Access, the Application Folder is located in C:\Windows\Web\PowerShellWebAccess\wwwroot
Configure PowerShell Web Access Gateway using the following PowerShell Cmdlet.
Do one of the following to open a Windows PowerShell session.
Type the following, and then press Enter.
The following settings are configured by running the cmdlet. You can change these manually in the IIS Manager console, if desired.
At this stage you can see the PowerShell Web Access Application Pool configured in IIS Manager & also verify the same using the Web Browser. IMP Note: You cannot sign in until users have been granted access to the website by adding authorization rules.
Step 2A: To verify the same in IIS Manager, open Server Manager –> IIS –> Right click on DPE-WS12-VM01 & click on Internet Information Services (IIS) Manager
Step 2B: You can also verify the same from Web Browser. Go to CLIENT machine i.e. DPE-WIN8-CLI01. Open Internet Explorer & open https://DPE-WS12-VM01/pswa As we are using Test Certificate you will see the warning. Click on Continue.
Note: In production environment you must configure security using valid SSL certificate signed from the certificate provider.
Step 2C: Once you click on Continue you will the following Windows PowerShell Web Access login page.
Note: For more information about supported browsers and devices, see Browser and client device support in this document.
Step 3: Configure Authorization Rule & Site Security. WE WILL PERFORM THE FOLLOWING USING POWERSHELL
Now, we need to allow certain users access to the Windows PowerShell Web Access.
Every Windows PowerShell session uses a session configuration; if one is not specified for a session, Windows PowerShell uses the default, built-in Windows PowerShell session configuration, called Microsoft.PowerShell. The default session configuration includes all cmdlets that are available on a computer. Administrators can restrict access to all computers by defining a session configuration with a restricted runspace (a limited range of cmdlets and tasks that their end users could perform). A user who is granted access to one computer with either full language access or only the Windows PowerShell remote management cmdlets can connect to other computers that are connected to the first computer. Defining a restricted runspace can prevent users from accessing other computers from their allowed Windows PowerShell runspace, and improves the security of your Windows PowerShell Web Access environment. The session configuration can be distributed (by using Group Policy) to all computers that administrators want to make accessible through Windows PowerShell Web Access. For more information about session configurations, see about_Session_Configurations. The following are some examples of this scenario.
In this example, An administrator has set up a private test environment, and wants to allow all authorized network users access to all computers on the network to which they typically have access, with access to all session configurations to which they typically have access. Because this is a private test environment, the administrator creates an authorization rule that is not secure. The administrator runs the cmdlet Add-PswaAuthorizationRule * * *, which uses the wildcard character * to represent all users, all computers, and all configurations.
Add-PswaAuthorizationRule * * *
This rule is the equivalent of the following: Add-PswaAuthorizationRule –UserName * -ComputerName * -ConfigurationName *
Add-PswaAuthorizationRule –UserName * -ComputerName * -ConfigurationName *
We will perform the above step in PowerShell on Domain Controller DPE-WS12-VM01
With the above PowerShell we have allowed all authorized network users access to all computers on the network with access to all session configuration to which they typically have access.
Let’s Try Now…
Step 3A: Go to CLIENT MACHINE DPE-WIN8-CLI01. Open Internet Explorer & open https://DPE-WS12-VM01/pswa & click on Continue (as specified we are using Test Certificate)
You can also check optional connection settings…
Step 3B: On the login screen enter your administrator credentials & specify destination computer. Click on Sign In.
Step 3C: You will see the following status Signing In…
Upon successful login you will PowerShell Window in the Web Browser.
You can start running cmdlets in the above box.
I hope you enjoyed this post. I am looking forward to hear from you. Enjoy.
Nice post....You are running free tech training program for us...:p
The services you're hosting the images from is being discontinued apparently. You've only got a couple of days to get them off the FTP it seems.
I apparently got the back up & will be upgrading that in next few days. Thanks much for your feedback :)
Hi, I am getting this error:
"The Windows PowerShell Web Access gateway cannot establish a connection to the destination computer. Contact the gateway administrator."
I am not using a AD controller, am using WORKGROUP with a self signed certificate
