WinRM Windows Remote Management

 Windows Remote Management (WinRM)?

WinRM is based on the Web Services for Management (WS-Management) standards. What that means is that WinRM uses the HTTP protocol (port 80). The good thing about that is that HTTP request are easy to send and receive through a firewall. The other benefit to WinRM using HTTP is that no additional ports would have to be opened up on server & client firewalls if HTTP inbound was already permitted.

WinRM has a command line interface with a lot of options. This help information for WinRM will show up even if WinRM isn’t “enabled” or “listening” on your system.

Configuring WinRM :

To set the default configuration type:

winrm quickconfig (or the abbreviated version, winrm qc)

‘winrm qc’ performs the following operations:

  1. Starts the WinRM service and sets the service startup type to auto-start.
  2. Configures a listener for the ports that send and receive WS-Management protocol messages using either HTTP or HTTPS on any IP address.

If ‘winrm qc’ throws an error:

If the firewall is disabled the quick config command will fail. The firewall can either be started in Services long enough to run ‘winrm qc’ or the commands below can be run:

sc config “WinRM” start= auto

net start WinRM

winrm create winrm/config/listener?Address=*+Transport=HTTP

netsh firewall add portopening TCP 80 “Windows Remote Management”

Group Policy configuration:

WinRM can be configured by group policies.

  1. Type gpedit at a command prompt. The Group Policy Object Editor window opens.

Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows component -> Window Remote Management (WinRM).

How do I use WinRM?

Open Command Prompt -> Run as Administrator

Type Winrm help -> enter

C:Windowssystem32>winrm help
