Win 10 WSUS Only doesnt work for Malicious software removal tool

[ITGURU]

I have a server 2016 server set up as a WSUS server for Windows 10 clients.

Whenever I approve updates, only the Malicious software removal tool updates won't download. I've tried august, september, and october updates. I get the message in the screenshot below.

I can retry and download but it fails everytime and nothing reported in the application log.

 

 

however if i approve any other windows update i.e cumulative updates, these will download without any issues, then when i check for updates on clients it will download and successfully install.

 

I just cannot get any of the malicious tool updates to download.

 

Can anyone help please?

Have you tried running the wsusutil reset command?

 

If not, perhaps try the server cleanup wizard?

Done both.

Even cleared out the folder.

I could then re-download already approved updated, but the malicious tool ones still won't download - says failed.

Sorted - I did a comparison on an existing working server.

Turns out the .exe files were being blocked on the filter despite the source IP being a bypass as the others were .cab files!

All working now.
