OneDrive On-Demand issues Server 2019 with FsLogix

josvds 

It appears that you are encountering issues with OneDrive's On-Demand functionality in a Windows Server 2019 environment with FsLogix. This can indeed be a complex situation, especially when dealing with remote desktop environments and file redirection. The error you provided ("Attach failed with error: 0x801f0013 - Kan het opgegeven filter niet vinden") suggests there might be problems with attaching the filter driver for Files On-Demand.

Here are some suggestions to troubleshoot and resolve this issue:

1. Registry Key Discrepancy: As you mentioned, there seems to be a registry key discrepancy between the servers. It is important to ensure that all necessary registry settings are properly configured for Files On-Demand. If some servers have the registry key and others do not, you should try adding the missing registry key and its values on the problematic server.
2. FsLogix Configuration: Since you are using FsLogix, ensure that your FsLogix configuration is consistent across all servers. Any inconsistencies might lead to issues with user profiles and file redirection. Verify that the version of FsLogix you are using is compatible with your Windows Server environment.
3. Filter Driver Attach Error: The error "Attach failed with error: 0x801f0013" indicates that the specified filter (cldflt) cannot be found. This might suggest a potential issue with the filter driver itself or how it is being loaded. Double-check the filter driver's availability and compatibility with your server version.
4. Windows Updates: Ensure that all servers are fully updated with the latest Windows updates and patches. Sometimes, issues can be resolved by updating the operating system to the latest version.
5. Event Logs: Check the Event Viewer logs on the server where you are experiencing the issue. Look for any relevant error messages or warnings related to OneDrive, FsLogix, or file system filters. This might provide more insights into the root cause of the problem.
6. Microsoft Support: Given the complexity of your environment and the specific error messages you are encountering, it might be beneficial to contact Microsoft Support. They can provide targeted assistance based on the details of your setup and troubleshoot the issue with you in real-time.
7. Testing in a Controlled Environment: If possible, set up a controlled environment to test the deployment of OneDrive On-Demand and FsLogix. This can help you isolate and troubleshoot the issue without impacting your production environment.
