![]() ![]() In the output, you should be able to see the default HTTP listener, assuming the server configuration hasn't been modified from the default settings. Open a PowerShell console with local administrator privileges, and run the command below: Enumerate WinRM listenersīefore we start configuring an HTTPS WinRM listener, let’s take a look at the existing listeners configured in Windows Server 2012 R2. PowerShell Remoting is enabled by default in Windows Server 2012 and later. ![]() If not, run the Enable-PSRemoting cmdlet in an elevated PowerShell console before continuing. The following instructions assume that PowerShell Remoting is enabled on the device where the HTTPS WinRM listener will be configured. ![]() Adding a remote device to the local TrustedHosts list is OK in a lab, but in a production environment, TrustedHosts doesn’t provide a high level of assurance that remote devices can be trusted. But in a workgroup, either you have to add remote devices to the TrustedHosts list or you should configure an HTTPS WinRM listener and install certificates to establish trust between the local and remote devices. In an Active Directory environment, Kerberos provides assurance that the remote device is trusted. Secure Sockets Layer (SSL) isn’t required to ensure that data is encrypted across the wire. Before data is sent to a remote device, it is serialized and encrypted. ![]() Windows Server is configured out-of-the-box with an HTTP WinRM listener. WinRM is the protocol behind PowerShell Remoting, which allows cmdlets and scripts to securely run on remote devices, with the results being sent back to the originating PowerShell console. Windows Remote Management (WinRM) is Microsoft’s implementation of WS-Management, a SOAP-based protocol that can traverse firewalls and is used to manage infrastructure devices and operating systems from different vendors. In today’s Ask the Admin, I’ll show you how to configure a Windows Remote Management (WinRM) HTTPS listener using a self-signed certificate. ![]()
