[SOLVED] Unable to install Windows Defender role due to 0x800F0831 Server A

[Da_Jester]

Hello Sysnative Team,
Hope all is well with everyone.
We are encountering yet a similar issue that was once resolved by Mr. @Maxstar (he rocks \m/) and in need of assistance to resolve 2 servers.

Thank you in advance and greatly appreciated as always.

Hi,

I've copied the logs for Server B to a new thread: Unable to install Windows Defender role due to 0x800F0831 Server B

Here's the fix Server A.

Step 1. Download

SFCFix and save it to your desktop.

Warning: This fix was written specifically for this system. Do not run this fix on another system.

• Save any work you have open, and close all programs.
• Download the attachment SFCFix.zip and save it to your desktop.
• Drag the SFCFix.zip file over the SFCFix.exe executable and release it.

• SFCFix will launch, let it complete.
• Once done, a file will appear on your desktop, called SFCFix.txt.
• Post the logfile (SFCFix.txt) as attachment in your next reply.

Step 2. Run the following DISM command and post the result. If it fails attach a new copy of the CBS log.

DISM /online /cleanup-image /RestoreHealth

Still failed sir and per your request, I've attached files from ServerA.

Hi,

Start the

Farbar Recovery Scan Tool again.

• Download the attachment fixlist.txt and save it to your desktop.
• Right-click on FRST.exe and select "Run as administrator".

Afterwards try to install the Windows Defender feature and post the result. If it fails attach a new copy of the CBS logs.
