In Citrix DaaS console, a MCS catalog creation failed at 'Image Preparation' stage with error message No Image Preparation results found. There may be no suitable VDA installed, or some other serious failure in the Master VM. Image preparation failed.

In the PrepVM, ImagePreparation.exe failed to write the result file 'PreparationStatus.xml' to 'C:\Program Files\Citrix\PvsVm\Service\PersistedData\' with error MEDIA WRITE PROTECTED. It is caused by Microsoft Intune process deviceenroller.exe applied FDVDenyWriteAccess=1 registry value in the PrepVM, which is equivalent to Microsoft BitLocker policy setting "Deny write access to fixed drives not protected by BitLocker".

Remove the master image VM from the management of Microsoft Intune. Then MCS image preparation is properly done and the machine catalog is successfully created.
