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

[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,

Step 1. Download

SFCFix and save it to your desktop.

• 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

Step 3. Follow these instructions to remove an update.

• Open the Start menu of Windows and type the command CMD
• When you see Command Prompt on the list, right-click on it and select Run as administrator.
• When command prompt opens, copy and paste the following command into it, then press enter.

wusa /uninstall /KB:4494175

• Let me know if it says it was successful or you get the message: The update KB4494175 is not installed on this computer.

Hello good sir,

SFCFix failed. Run DISM and received this error:

Image Version: 10.0.14393.4169

[==========================100.0%==========================]

The array bounds are invalid.

The DISM log file can be found at C:\windows\Logs\DISM\dism.log

WUSA message:

The system cannot find the file specified.

Hi,

Are you sure you've used the SFCFix.zip file from post #4? Please run that fix again and post the new result.
