NEW ADR - Defender not downloading definition files automatically

[Mike]

Hi All

I have an issue with an ADR for my defender updates - when the ADR runs it is not downloading the latest definition updates to the source folder - this used to work before

As a test I created a manual download under the normal "updates" and it did download the required definition updates to a source folder

i have also read on another forum that you should clean up the following folder

C:\windows\temp folder - in this folder i have removed all of the CAB!.tmp files that were 0kb in size - after i did this It work for 1 sync but stopped right there after again
Please take note that the ADR completes without any error messages of failures - however the source folder remains empty

what else can I do to resolve this

I also compared this to one of my other clients that is also using Defender and all the settings are the same
thx in advance

I ran into this issue recently, besides clearing the C:\windows\temp folder entirely and rebooting the server, we had to clear the WSUS that our system was pointed to. We had about 65k updates to clear out and took about a week with scripts.
