Windows Server 2016 - Issues installing defender

[Christoffer]

Hi,

We have RDP-servers that we are trying to install Defender for Endpoint on and we have problem installing it.
Seems to be Windows Update-related.

One of the servers was solved with this thread: [SOLVED] - Windows Server 2016

We get the same issues like in that thread.

On all of the servers we get "Please update Windows Defender Antivirus (KB4052623) to the latest version." in the installation process.

Ive tried to manuallt install the KB, and a different solution was to install Windows Defender Features under Add Roles and Features.

This worked on one of our RDP-servers, but the other two I have a lot of problems doing this.
When I try to install the feature I receive error 0x80073701.

Ive tried to run the Troubleshooter for Windows Update and it says "Repair Windows Update Database Corruption".
When I apply that fix, it gives me the that there is a "Potential Windows Update Database error detected" which it cant fix.

I go over to do a SFC /scannow.

Results:

---

C:\Windows\system32>sfc /scannow
Beginning system scan. This process will take some time.

Beginning verification phase of the system scan.
Verification 100% complete.

Windows Resources Protection did not find any integrity violations.

---

Then I do DISM command and I receive this:

---

C:\Windows\system32>DISM /Online /Cleanup-image /RestoreHealth /source:\Sources\install.wim:4 /limitaccess

Deployment Image Servicing and Management tool
Version: 10.0.14393.4169

Image version: 10.0.14393.7426

[====================100.0%====================]
Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required to restore the feature. For more information on specifying a source location, see Statistics Used by the Query Optimizer in Microsoft SQL Server 2008.

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

Attatching the CBS and ComponentsScanner.txt!

Hi,

Step 1:
Remove Update Manually

1. Right-Click the Start button and click Command Prompt (Admin) on the list.
2. When command prompt opens, copy and paste the following command into it, then press enter.
   wusa /uninstall /KB:4338814
3. Let me know if it says it was successful or if there are any errors.

Step 2:
FRST Registry Search

1. Click the Start button and in the search box, type CMD
2. When you see cmd.exe on the list, right-click on it and select Run as administrator.
3. When command prompt opens, copy and paste the following command into it, press enter afterwards.
   
   

   REG LOAD HKLM\COMPONENTS C:\Windows\System32\config\COMPONENTS

   
   Note: This loads your components hive which is what we want. Please keep the command prompt window open while you perform the remaining steps. You can minimize it if you wish but keep it open.
4. Download the Farbar Recovery Scan Tool and save it to your Desktop:
   64-bit: Downloading Farbar Recovery Scan Tool
   Note: Your antivirus program may report FRST incorrectly as an infection. If so, disable the real-time protection when downloading and running FRST.
   
5. Right-click on the file FRST64.exe and choose Run as administrator.
6. Copy and paste KB4338814 into the Search box and click the Search Registry button.
7. When the scan is complete, a message will display that 'SearchReg.txt' is saved in the same folder FRST was started from. Notepad will open this file also. Close Notepad and attach the file 'SearchReg.txt' to your next reply.
8. You may close any remaining open windows now.
