Hello
There could be several reasons why your WSUS client agent is not working correctly. Some common issues include:
1. Incorrect group policy settings: Ensure that the correct group policy settings are applied to the client machines to point them to the WSUS server.
2. Firewall or network issues: Make sure that there are no firewall rules blocking communication between the WSUS server and the client machines.
3. Client not reporting to WSUS server: Verify that the client machines are reporting to the WSUS server by checking the WindowsUpdate.log file on the client machine.
To verify that the WSUS client is configured correctly, you can follow these steps:
1. Check the Windows Update settings: Open the Windows Update settings on the client machine and make sure that it is configured to receive updates from a WSUS server.
2. Check the Windows Update registry keys: Check the registry keys on the client machine to ensure that the correct settings are applied. You can check the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate registry key.
3. Run the Windows Update troubleshooter: Run the Windows Update troubleshooter on the client machine to identify and fix any issues with the Windows Update service.
4. Check the WSUS server settings: Make sure that the WSUS server is configured correctly and that it is reachable from the client machines.
