Description

This resource is responsible for ensuring the installation of all SharePoint prerequisites. It makes use of the PrerequisiteInstaller.exe file that is part of the SharePoint binaries, and will install the required Windows features as well as additional software. The OnlineMode boolean will tell the prerequisite installer which mode to run in, if it is online you do not need to list any other parameters for this resource. If you do not use online mode, you must include all other parameters to specify where the installation files are located. These additional parameters map directly to the options passed to prerequisiteinstaller.exe. For installations with no connectivity to Windows Update, use the SXSpath parameter to specify the path to the SXS store of your Windows Server install media.

Additionally, the process of installing the prerequisites on a Windows Server usually results in 2-3 restarts of the system being required. To ensure the DSC configuration is able to restart the server when needed, ensure the below settings for the local configuration manager are included in your DSC file.

LocalConfigurationManager
{
    RebootNodeIfNeeded = $true
}
