Some Windows Client Computer does not get Windows Updates using SCCM

Hi,

I deploy my monthly Windows Updates with ADR on the SCCM. Some Computers does not get the windows updates.

If I check the log file of "WUAHandler.log", I see the folloing error

OnSearchComplete - Failed to end search job. Error = 0x8024001e.

and

Scan failed with error = 0x8024001e.

My steps to resolve it

1. troubleshot windows update
2. rename SoftwareDistribution and create a new one
3. rename caroot2 and create a new one
4. rename the grouppolicy unter :\Windows\System32\GroupPolicy and create a new one

No solution.

if go the probertites of the client machine under Deployment, I see there the windows Updates I deployed

any Idea?

Regards
