In this post we will see how you can configure WinRM (Windows Remote Management) service to work with HTTPS manually.

Configuring for HTTPS involves following steps.

  • Check whether WinRM service is running
  • Create HTTPS listener
  • Add firewall exception
  • Validate HTTPS listener
  • Verify you can connect to the machine via HTTPS

For the demo purposes I have built a new VM using AzureDevTestLab. We will perform the above steps in this VM and enable it for HTTPS communication.

Check whether WinRM service is running

WinRM is installed by default in all supported Windows machines. Ensure that service is in running state in services.

Service Status

Create HTTPS listener

By default when you run winrm quickconfig command WinRM is only configured for HTTP (port 5985). You can check already registered listeners by running following command.

WinRM e winrm/config/listener

You will see output like below.

WinRM Listener

To enable HTTPS for WinRM, you need to open port 5986 and add HTTPS listener in the VM.

Before we start doing that, we will first need to create a self-signed certificate and get its thumbprint. To create a self signed certificate we can use either makecert command or a New-SelfSignedCertificate powershell commandlet. I am using powershell commandlet here. Open your powershell window in Adminstrator mode and run the below command.

New-SelfSignedCertificate -DnsName "<YOUR_DNS_NAME>" -CertStoreLocation Cert:\LocalMachine\My

This command will create a new self signed certificate and output the certificate thumbprint.

WinRM Self Signed Certificate

DNS name used in the above command is your machine hostname and for Aure portal VM’s you can get it from the portal from VM properties.

WinRM DNS Name

Copy the thumbprint to clipboard and run the following command. This command will register the HTTPS listener in WinRM

winrm create winrm/config/Listener?Address=*+Transport=HTTPS @{Hostname="<YOUR_DNS_NAME>"; CertificateThumbprint="<COPIED_CERTIFICATE_THUMBPRINT>"}

You will see output as below.

WinRM HTTPS Listener

Add firewall exception

Via Firewall applet from Control Panel

  • Open Windows Firewall from Control Panel
  • Go to Inbound Rules then click New Rule
  • This will open the wizard

WinRM Firewall Wizard

  • Select Port and then TCP
  • Enter port as 5986

WinRM Firewall Port

  • In the next screens select Allow the connection
  • In the profile page check all the checkboxes.
  • Finally give a name to the rule.

Via command

You can also do the same operation and add firwall exception for port 5986 by running the following command in powershell console as Administrator.

# Add a new firewall rule
netsh advfirewall firewall add rule name="Windows Remote Management (HTTPS-In)" dir=in action=allow protocol=TCP localport=$port

WinRM Firwall Port Add

Validate HTTPS listener

You can verify listener you added by running the same command you used above - WinRM e winrm/config/listener. This will show the new HTTP listener now along with previous HTTPS listener.

WinRM HTTPS Listener

Verify you can connect to the machine via HTTPS

We have done with your WinRM configuration and now we need to verify we can connect to this VM using HTTPS.

Run the following commands in powershell window as Administrator

$hostName="<DNS_NAME>" # example: ""
$winrmPort = "5986"

# Get the credentials of the machine
$cred = Get-Credential

# Connect to the machine
$soptions = New-PSSessionOption -SkipCACheck
Enter-PSSession -ComputerName $hostName -Port $winrmPort -Credential $cred -SessionOption $soptions -UseSSL

On entering the last command, you will be logged in to remote machine’s powershell session. As you can see in the screenshot below, you are connected and you can get the items from the remote virtual machine.

WinRM Validate

That is it then. You can read these other great blog posts on WinRM, AzureDevTestLab and DevOps.
