How to manually configure the Windows Management Framework

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

Launch Command Prompt as Administrator.
Run the following command and look for the version:
PowerShell.exe Get-Host

Configuring WinRM 2.0

Launch Command Prompt as Administrator:

winrm quickconfig -q
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

Launch Command Prompt as Administrator.
Run the following command and follow the prompts to enable WinRM:

winrm quickconfig -q
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"}
