server 2016 0x80073701

Question

Hi all,

When trying to add the AD role to server 2016 I am getting the error: 0x80073701. I am able to add DHCP and DNS role, just not AD. I tried running SFC/ Scannow now and it finds errors but cannot repair. I also tried running the DISM repair commands without luck. I searched he CBS log for ERROR_SXS_ASSEMBLY_MISSING and it finds a particular KB missing, Package_5445_for_KB4512495. I've searched the web but cannot seem to locate it.

thoughts or suggestions please

Answer 1

0x80073701 = ERROR_SXS_ASSEMBLY_MISSING which means there are some system files are missing, which caused the update installation failure. You can try uninstalling KB4512495, reboot, install the latest SSU
https://www.catalog.update.microsoft.com/Search.aspx?q=KB4576750

followed by the latest cumulative update.

Answer 2

Thanks for the feedback. I do not see KB4512495 listed under control panel, view installed updates. I will try to install the latest SSU.

Answer 3

Sounds good, if a later cumulative update has been installed then KB4512495 is superseded. Another option is a repair install by running setup.exe from the root of the install media, but time may be better spent standing up a new one, patch fully, and migrate the roles over to it.

Answer 4

It looks like the first update is already installed. When trying to install https://www.catalog.update.microsoft.com/Search.aspx?q=KB4586830 I get the error "the update is not applicable to your computer"

Answer 5

looks like the first update is already installed

Yes, I'd agree. The only way to uninstall an older cumulative update is to uninstall them in reverse order they were installed. I wouldn't hold much hope for this process.
