  • Attach that file to your next reply.

Step 2:
Restart the machine.
Run the command sfc /scannow in an elevated commandprompt and report the result.

Thank you, the earliest I can reboot this server is Saturday this weekend. I'll keep you informed.
 
Ok, no problem.
 
2025-01 Cumulative Update for Windows Server 2016 for x64-based Systems (KB5049993) still fails to install. SFC /scannow after fix said:

sfc /scannow

Beginning system scan. This process will take some time.

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

Windows Resource Protection did not find any integrity violations.

DISM /RestoreHealth Scan
  1. Right-click the Start button and select Command Prompt (Administrator)
  2. If you get a popup about UserAccountControl, allow the program to run.
  3. When command prompt opens, copy and paste the following commands into it, press enter after each.
    Code: 
    Dism /Online /Cleanup-Image /RestoreHealth
    Wait for this to finish before you continue

    Code: 
    copy %windir%\logs\cbs\cbs.log "%userprofile%\Desktop\cbs.txt"
  4. This will create a file, cbs.txt on your Desktop. Please attach this to your next post.
    Note: if the file is too big to upload to your next post please upload via a service such as Gofile or WeTransfer and just provide the download link.
 
I ran this DISM today:

Dism /Online /Cleanup-Image /RestoreHealth

Deployment Image Servicing and Management tool
Version: 10.0.14393.0

Image Version: 10.0.14393.0

[==========================100.0%==========================]
Error: 1726

The remote procedure call failed.

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

This happened on Sunday when I ran DISM after the SFC /scannow, after the sfcfix.exe.

The update got to 100% and then still failed with:
2025-01 Cumulative Update for Windows Server 2016 for x64-based Systems (KB5049993) - Error 0x80073701

I've been given the green light to reboot this server tonight, so I'll try again then, if there's nothing else for now.

Provide a fresh copy of the file cbs.log.
 
The cbs.log rolled over.
Provide the newest file CbsPersist_<date><time>.log or .cab
