By default WinRM uses Kerberos for authentication so Windows never sends the password to the system requesting validation. To get a list of your authentication settings, type the following command:

winrm get winrm/config

The purpose of configuring WinRM for HTTPS is to encrypt the data being sent across the wire.

WinRM HTTPS requires a local computer Server Authentication certificate with a CN matching the hostname to be installed. The certificate mustn't be expired, revoked, or self-signed.

To install or view certificates for the local computer:

  1. Select Start and then select Run (or using keyboard combination press Windows key+R)。
  2. Type MMC and then press Enter.
  3. Select File from menu options and then select Add or Remove Snap-ins.
  4. Select Certificates and select Add.
  5. Go through the wizard selecting Computer account.
  6. Install or view the certificates under Certificates (Local computer) > Personal > Certificates.

If you don't have a Server Authenticating certificate, consult your certificate administrator. If you have a microsoft Certificate server, you may be able to request a certificate using the web certificate template from HTTPS://<MyDomainCertificateServer>/certsrv.

Once the certificate is installed type the following to configure WINRM to listen on HTTPS:

winrm quickconfig -transport:https

If you don't have an appropriate certificate, you can run the following command with the authentication methods configured for WinRM. However, the data won't be encrypted.

winrm quickconfig

More information

By default, on Windows 7 and later versions, WinRM HTTP uses port 5985 and WinRM HTTPS uses port 5986. On earlier versions of Windows, WinRM HTTP uses port 80 and WinRM HTTPS uses port 443.

To confirm WinRM is listening on HTTPS, type the following command:

winrm enumerate winrm/config/listener

To confirm a computer certificate has been installed, use the Certificates MMC add-in or type the following command:

Winrm get

If you get the following error message:

Error number: -2144108267 0x80338115
Message = Cannot create a WinRM listener on HTTPS because this machine does not have an appropriate certificate.

To be used for SSL, a certificate must have a CN matching the hostname, be appropriate for Server Authentication, and not be expired, revoked, or self-signed.

Open the certificates MMC add-in and confirm the following attributes are correct:

  • The date of the computer falls between the Valid from: to the To: date on the General tab.
  • Host name matches the Issued to: on the General tab, or it matches one of the Subject Alternative Name exactly as displayed on the Details tab.
  • That the Enhanced Key Usage on the Details tab contains Server authentication.
  • On the Certification Path tab that the Current Status is This certificate is OK.

If you have more than one local computer account server certificate installed, confirm the Certificate Thumbprint displayed by Winrm enumerate winrm/config/listener is the same Thumbprint on the Details tab of the certificate.
