Hi, @rakesh ck
Thank you for posting in Microsoft Q&A forum.
Here are some troubleshooting steps you may check for the error code 0x80D02002:
- Check Delivery Optimization Settings: Ensure that the Delivery Optimization settings are configured correctly for your environment. Misconfigurations can lead to issues with downloading updates.
- Review Logs: Since you mentioned the DataTransferService.log and DeltaDownload.log, check these logs for any specific errors or warnings that might provide more insight into the issue.
- Retry the Download: As you've noted that sometimes updates download successfully after retrying, it may be worth implementing a scheduled retry mechanism for updates.
- Network Configuration: Even though you mentioned no proxy is configured, ensure that there are no firewall rules or network policies that could be impacting the download of security updates.
- Update Configuration Manager: Ensure that your Configuration Manager is up to date with the latest hotfix. Sometimes, known issues are resolved in newer versions.
- Disable Branch Cache: If Branch Cache is enabled, consider disabling it temporarily to see if that resolves the issue, as it can sometimes interfere with downloads from the CMG.
