It is possible that the two servers have different configurations or software installed, causing them to require different updates. Additionally, some updates may only be applicable to specific components or features that one server has but the other does not. It is important to review the details of each update to understand why it is needed or not applicable for a particular server.
To fix WSUS update issues, you can try the following steps:
- Check the WSUS server configuration: Make sure that the WSUS server is properly configured and all settings are correct.
- Check the update status of the client computers: Verify that all client computers are properly reporting to the WSUS server and that they are receiving updates.
- Check the update approval settings: Ensure that the updates are approved for the correct groups of computers and that the approval settings are correct.
- Reset the WSUS server: If the above steps do not work, you may need to reset the WSUS server. This will delete the update history and start fresh.
- Troubleshoot individual updates: If a specific update is causing problems, you can troubleshoot it by checking the update status and logs, and then manually installing the update.
- Update WSUS server: Make sure that the WSUS server is updated with the latest patches and updates.
