This script improve and update the way to check the configuration on NDES based server on previous Validate-NDESConfig, and ensures it aligns to the "Configure and manage SCEP certificates with new Intune certification connector. This is based on https://github.com/microsoftgraph/powershell-intune-samples/blob/master/CertificationAuthority/Validate-NDESConfiguration.ps1 Validates and highlights configuration problems on an NDES server installed new Intune certificate connector。 After installing the script, run "Validate-NewIntuneNDESConfig.ps1" directly. NOTE: This script is used purely to validate the configuration. All remedial tasks will need to be carried out manually.
