Configure WinRM for HTTPS

    Configure WinRM for HTTPS manually

    Configuring for HTTPS involves following steps.

      • Check whether WinRM service is running
      • Create HTTPS listener
      • Add firewall exception
      • Validate HTTPS listener

    Check whether WinRM service is running

    Get-Service WiRM

    PS C:\Users\wintel> Get-Service WinRM
    
    Status  Name  DisplayName
    ------  ----  -----------
    Running WinRM Windows Remote Management (WS-Manag...​

    If the WinRM service is not running, you might need to configure WinRM using winrm quickconfig. When you configure winrm first time, it is configured to use 5985 by default.

    check already registered listeners by running following command

    PS C:\Users\Administrator> WinRM e winrm/config/listener
    Listener
    Address = *
    Transport = HTTP
    Port = 5985
    Hostname
    Enabled = true
    URLPrefix = wsman
    CertificateThumbprint
    ListeningOn = 127.0.0.1, 172.20.20.1, ::1, fe80::5efe:172.20.20.1%15, fe80::d071:b058:c541:a212%12

    Create HTTPS listener

    To create a HTTPS listener, you need to have a certificate.

    Generate SSL Certificate with one of these options

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

    C:\>winrm create winrm/config/Listener?Address=*+Transport=HTTPS @{Hostname="vc01.winadmin.org";CertificateThumbprint="9a20b7dab60933e3ce2ba6fddc02025dcdb83558"}
    
    ResourceCreated
    Address = http://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous
    ReferenceParameters
    ResourceURI = http://schemas.microsoft.com/wbem/wsman/1/config/listener
    SelectorSet
    Selector: Address = *, Transport = HTTPS​

    Add firewall exception

    You can use command and GUI tool to configure firewall exception.

    Via command

    # Add a new firewall rule

    netsh advfirewall firewall add rule name="Windows Remote Management (HTTPS-In)" dir=in action=allow protocol=TCP localport=5986

    Using Windows Firewall with Advanced Security GUI tool.

    Open Windows Firewall with Advanced Security and click New Rule.
    Configuring WinRM 1

    Select Port
    Configuring WinRM 2

    Specific local ports – Enter 5986
    Configuring WinRM 3

    Select Allow the connection
    Configuring WinRM 4

    Select the options whatever is required
    Configuring WinRM 5

    And give a name and click Finish
    Configuring WinRM 6

    Now check the WinRM Listener. The output should be as follows.

    C:\>WinRM e winrm/config/listener
    
    Listener
      Address = *
      Transport = HTTP
      Port = 5985
      Hostname
      Enabled = true
      URLPrefix = wsman
      CertificateThumbprint
      ListeningOn = 127.0.0.1, 172.20.20.2, 192.168.20.2, ::1, fe80::5efe:172.20.20.2%17, fe80::5efe:192.168.20.2%16, fe80::1c21:cbdc:66d9:967%12, fe80::4d34:b19b:402c:ae3a%13
    Listener
      Address = *
      Transport = HTTPS
      Port = 5986
      Hostname = vc01.winadmin.org
      Enabled = true
      URLPrefix = wsman
      CertificateThumbprint = 9a20b7dab60933e3ce2ba6fddc02025dcdb83558
      ListeningOn = 127.0.0.1, 172.20.20.2, 192.168.20.2, ::1, fe80::5efe:172.20.20.2%17, fe80::5efe:192.168.20.2%16, fe80::1c21:cbdc:66d9:967%12, fe80::4d34:b19b:402c:ae3a%13

    Verify you can connect to the machine via HTTPS

    PS C:\Users\Administrator> Enter-PSSession -Cn vc01.winadmin.org -UseSSL
    [vc01.winadmin.org]: PS C:\Users\wintel\Documents>

    If you give only host name, it will give errors and will not connect.

    PS C:\Users\Administrator> Enter-PSSession -Cn vc01 -UseSSL
    
    Enter-PSSession : Connecting to remote server vc01 failed with the following error message : The server certificate onthe destination computer (vc01:5986) has the following errors:
    The SSL certificate contains a common name (CN) that does not match the hostname. For more information, see theabout_Remote_Troubleshooting Help topic.
