Download error - 0x80d02002 on WSUS Client

need more information - likely it is a group policy or a client side issue that's causing the error.

Follow my guide here:

run through from the client side each step under troubleshooting to see if it's an issue at the client side.

Hello, I know it's an old thread but if someone get's in here I wanted them to know how I resolve this issue in my environment:

The issue that prevented updates on Windows 11 machines has been resolved. Root cause – IIS did not recognize the .wim file extension required for downloading updates. Below is the full process for the benefit of the team.

Issue Identification Process:

Error code encountered in all previously failed updates: 0x80d02002

1.While the update was stuck at the Downloading stage, I ran the following command in PowerShell to get more details: Get-DeliveryOptimizationStatus

2.In the attached screenshot, you can see the status was stuck on "downloading" (which eventually returns the error code above), and you can also see the URL it was trying to access to download the update.

3)the issue was with the client or the WSUS, I tried accessing the mentioned URL directly but received a 404 error, as if the file was not present on the server.

4)On the WSUS server, I checked whether the file existed in the WSUS directory: C:\WSUS\WsusContent\D0\3F57A1D919EDE163FFECC60BEA0FF8FBFEBD4AD0.wim and confirmed that it was indeed there.

5)Finally, I found the root cause was in IIS, under Sites > WSUS Administration > MIME Types. It appeared that the .wim extension (the type of file we were trying to access) was not recognized by IIS.

6)I added a new MIME type entry with the following details:

• File name extension: .wim
• MIME type: application/octet-stream

After that, I ran IISRESET. The URL that previously returned a 404 error now worked and successfully downloaded the file. Updates resumed immediately after.
