Solve remote PowerShell errors trying to enable cluster aware updating.

Q. I'm trying to enable cluster-aware updating on Windows Server 2016 but I have errors related to remote PowerShell and firewall ports, what can I do?

A. On some systems I've seen problems related to remote PowerShell execution and remote shutdown. To solve the problems perform the following on the problem nodes:

1. To enable PowerShell remoting run:
   Enable-PSRemoting - force
2. To confirm the state use:
   get-service winrm
3. To enable the remote rule to enable remote shutdown open Windows Firewall with Advanced Security
4. Set Inbound Rule for Remote Shutdown (RPC-EP-In) to Enabled
