You might see either or both of these errors in your Event Viewer:

Log Name: System  Source: Microsoft-Windows-WinRM
Event ID: 10149    Level: Warning  Keywords: Classic

Description: The WinRM service is not listening for WS-Management requests.
User Action If you did not intentionally stop the service, use the following command to see the WinRM configuration: winrm enumerate winrm/config/listener

or

Log Name: System Source: Microsoft-Windows-WinRM
Event ID: 10155

Description: The WSMan service failed to read configuration of the following plugin:
Microsoft.ServerManager.
The WS-Management service cannot process the request. Configuration for plugin: “Microsoft.ServerManager” is corrupted. This plugin needs to be reconfigured or deleted. Use the following command to delete a plugin configuration

winrm delete http://schemas.microsoft.com/wbem/wsman/1/config/plugin?Name=xyz

Or use the following command to restore default plugin configuration. Note that all external plugins will be unregistered during this restore operation.

winrm invoke Restore http://schemas.microsoft.com/wbem/wsman/1/config/plugin @{}.

User Action Make sure this plugin configuration is valid.

There are two common causes both with easy solutions:

FIX 1 – Add IP Addresses To The Monitor

See if ALL your IP’s are being monitored.  That includes your IPv4 address (or addresses if you have more than 1) AND the loopback 127.0.0.1.

You can do this by just running this command: netsh http show iplist

You can see in my case it was not configured to listen to any IP addresses:

netsh http show iplist WinRM Corrupt or Missing

If you need to add your IP’s just use netsh http add iplisten 127.0.0.1

netsh http add iplisten WinRM Corrupt or Missing


FIX 2 – Correct Registry

The registry entries for WinRM and WSMan should look like:

Registry Entry for Server Manager could not start the task due to the following error Failed to open

 

 

 

If your is empty or missing settings, here are the defaults taken from a fresh Windows Server 2012 R2 install:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN]
“StackVersion”=”2.0”

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WSMAN\AutoRestartList]

Note that I copied the setting above from THIS great website.
