Hi,

I am having trouble performing a windows update on a windows server 2012 R2 box.

Everytime i go to update it, the box freezes at downloading 0%. If i try to stop the download, the process and service seem to freeze and the only way to move forward is to taskkill /f on the process for wuauserv. 

I have tried running a dism.exe cleanup and deleting the %windir%\SoftwareDistribution\Download folder as ive seen in some other threads but neither have given me any success.

I also tried running individual updates one at a time and still seem to freeze up.

from the update log file I'm seeing error 0x80240037 but im not sure what to make of it and research on the error hasn't helped much. 

Below is a snippet of the windowsupdate log file.  Any help would be greatly appreciated.

0x80240037 is nothing to worry about, this is an "expected" error/warning if the computer is connected to a wired network.

Keep looking through the WindowsUpdate.log - nothing else you've shown us above describes any errors at all..

Hi,

Does the server update from Microsoft Update?

Is there any firewall or proxy between the server and the update source?

If yes, please make sure that the proxy supports HTTP1.1 .

Also, have you tried "sfc /scannow" on the server?

Best Regards.
