How to manually configure the Windows Management Framework

  • Last updated on

Starting with Barracuda RMM 2013 R1 FP3, the Barracuda RMM Onsite Managers will now be querying WMI over the WS-Management Protocol. If the WS-Management protocol is not available on a device, Barracuda RMM Onsite Manager will revert to querying WMI over DCOM.

In order to utilize WS-Man, Windows Management Framework (WinRM 2.0) or greater must be installed. Below are the steps required to configure the Windows Management Framework manually on a device.

  To determine the version of the Windows Management Framework
  1. Launch Command Prompt as Administrator.
  2. Run the following command and look for the version:

    PowerShell.exe Get-Host


Configuring WinRM 2.0
  1. Launch Command Prompt as Administrator:

     

    winrm quickconfig -q
  2. Run the following commands to apply the required configuration change

    winrm set winrm/config @{MaxEnvelopeSizekb = "2000"}
    winrm set winrm/config/client @{TrustedHosts="*"}
    winrm set winrm/config/client/auth @{Basic="true"}
    winrm set winrm/config/service @{EnumerationTimeoutms="240000"}
    winrm set winrm/config/service @{MaxConcurrentOperationsPerUser="1500"}
    winrm set winrm/config/service @{MaxConnections="50"}
    winrm set winrm/config/service/auth @{Basic="true"}
Configuring WinRM 3.0 or higher
  1. Launch Command Prompt as Administrator.
  2. Run the following command and follow the prompts to enable WinRM:

     

    winrm quickconfig -q
  3. Run the following commands to apply the required configuration changes

    winrm set winrm/config @{MaxEnvelopeSizekb = "2000"}
    winrm set winrm/config/client @{TrustedHosts="*"}
    winrm set winrm/config/client/auth @{Basic="true"}
    winrm set winrm/config/service @{EnumerationTimeoutms="240000"}
    winrm set winrm/config/service @{MaxConcurrentOperationsPerUser="1500"}
    winrm set winrm/config/service @{MaxConnections="300"}
    winrm set winrm/config/service/auth @{Basic="true"}
    winrm set winrm/config/service @{AllowRemoteAccess = "true"}

The script below is also available in the wiki which will automate the above manual process if all you want is to configure an existing Windows Management Framework.
