We have a 2016 Server that will not patch the update rollups. It has failed for a number of months apparently by the logs.
So I went through the following steps
sfc /scannow - it had errors.
So ran Dism /Online /Cleanup-Image /RestoreHealth and it had errors and couldn't complete.
Tried running SFCFix and it had errors
SFCFix version 3.0.2.1 by niemiro has encountered an unhandled exception.
Currently storing 0 datablocks.
Finish time: 2020-11-01 18:04:44.486
So ran
DISM.exe /mount-Image /ImageFile:G:\sources\install.wim /index:2 /mountdir:C:\mount\ /readonly
Deployment Image Servicing and Management tool
Version: 10.0.14393.0
Mounting image

---------------------------
Then tried to stop Windows Update Services and renamed Software distribution folder. Restarted services
Tried offline installer update for KB4580346 again and failed.
Looked through last CBS log and it refers to some errors with KB4503267
Failed to pin deployment while resolving Update: Package_1908_for_KB4503267~31bf3856ad364e35~amd64~~10.0.1.4.4503267-4886_neutral from file: (null) [HRESULT = 0x80073701 - ERROR_SXS_ASSEMBLY_MISSING]
So now stumped as to what to try as I can't find the KB4503267 update to download.
Thanks for any assistance you can provide.
