Windows Defender Issue on Windows Server 2016 with DPM

Hello All

Almost 2 weeks ago our backups stopped working totally. It would just stand still and eventually fail. Today i was informed that this might be a windows defender bug with DPM. And i can confirm it is. Working with MS Support on a permanent fix for this issue.

I initially thought it was a Database bug. But it’s defender.

If one open up Performance Monitor it will hang for a long time. Like this

How to disable Windows Defender the Right Way

So i tried to disable defender by going in to Windows Settings | Windows Defender and turn off it there. But that did not work. What i had to do was go in to local group policy editor and go to

Computer Configuration | Administrative Template | Windows Components | Windows Defender

And then Turn off Windows Defender.

Now you will se your backups working again.

    Opened a ticket with MS 6-27. Read this on 7-7. Few minutes later it was syncing clients again. Spoke with the MS tech today and let them know this resolved. I was informed the official release will be in UR4, no release date currently, but they are releasing it as a “Private fix” if you meet the criteria for the bug.

      Im awaiting the feedback with ms about this my self. Hopefully they will come with a private fix soon. Il need to enable defender again 🙂 Thanks for the update.

    1. Im afraid i have not gotten a reply back from MS support on that as of now. And i have not turned it on again on the backup server.

      Will need to check that up.

      Thanks
