Hi, @SAURABH LALSARE
Thank you for posting in Microsoft Q&A forum.
The error code 0x80240438 in the WUAHANDLER log indicates that the update source is not found. This could be caused by several reasons, including a misconfiguration of the WSUS server or a firewall issue. To troubleshoot this issue, you can try the following steps:
- Verify that the WSUS server is configured correctly and that the client can communicate with it. Check the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
to find the URL of the WSUS server and try to access it from the client machine. - Check the firewall settings on the client machine and the WSUS server to ensure that they are not blocking communication between the two.
- Check the WindowsUpdate.log for any additional error messages that may provide more information about the issue.
- If the issue persists, try resetting the Windows Update Agent data store on the client machine by stopping the Windows Update service, renaming the
C:\Windows\SoftwareDistribution
folder toC:\Windows\SoftwareDistribution.old
, and then starting the Windows Update service again.
