Having issues getting any windows update to install. Even optional updates wont. get error code 80070490. this is on 3 different servers, all running Windows server 2012 R2 and the same error code is generated. doing testing on a print server so restart will not have as big as an impact as the file servers would have.

Ran the windows update troubleshooter, it discovered 3 errors but says it fixed the issues. Restarted server after and updates still will not install.

attempted to install an update manually. Says it installs but when i restart server it reverts to before the update was installed and acts like it wasnt installed and windows update continues to fail.

ran sfc /scannow as administrator. discovers file errors but cannot correct them.

ran dism /online /cleanup-image /checkhealth. this tells me the image is repairable.

ran dism /online /cleanup-image /restorehealth. this returns error code 0x800f0906 and says the source file could not be downloaded.

ran dism /Online /Cleanup-Image /StartComponentCleanup. this completes with no errors.

ran DISM /Online /Cleanup-Image /AnalyzeComponentStore. this also completes successfully with no errors.

tried to do dism offline with a mounted iso file. ran dism /Online /Cleanup-Image /RestoreHealth /source:E:\Sources\Install.wim:1 /LimitAccess. this fails with error 0x800f081f. the source file could not be found.

i did notice that dism says the current version of the image is 6.3.9600.19397. I believe when i use the offline method it says the image version is 6.3.9600.19408. Would the image version differences cause this offline dism to fail? I am stuck at this point and am unsure of what to try next. I do not want to reload Server 2012, as i said before this is happening on 3 different servers that are being used daily. a long period of them being down will effect the whole company, not just this facility.

I do have all the log files i can share as well.
