Enabling Defender on Windows Server 2016

[JR97]

Hello,

I am having some issues with enabling Defender on a number of WS2016 boxes. Originally I was receiving the error "0x800f081f" when attempting to run "Dism /Online /Enable-Feature /FeatureName:Windows-Defender". Looking in my CBS log I found 34 packages/manifest files which were missing and these were successfully replaced following the steps in this article - Troubleshooting 0x800f081f / 0x800f0982 Error.

Since then, I have attempted to re-enable the feature but receiving a new error within the CBS log along the lines of [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]. I have attached the full log for reference.

I've downloaded KB5046612 and extracted 6 CAB files. From here I then tried re-installing the CAB files using DISM but this failed saying the source files couldn't be found.

Any help would be massively appreciated.

Thank you in advance!
