Windows 11 Pro (23H2) is running smoothly on your laptop except for the FDResPub service issue. The Function Discovery Resource Publication service isn’t active, and network printer discovery fails. Manual IP printer installs are functional, but the main problem persists. I’ve checked dependencies—RpcSs, http, fdPHost, SSDPSRV are all running—and created inbound firewall rules for FDResPub across profiles. The network profile uses private service registry values, and the service is set to Private. I ran several diagnostics: system is clean, svchost groups match, and the service account changed to LocalSystem succeeded. However, after a full scan, it still reported an error: “Feature unknown.” Event logs point to an account mismatch between FDResPub and its siblings. The service can’t start under LocalSystem because the account must align with sibling processes. I’ve tried running sfc /scannow and dism /online /enable-feature, but it keeps saying the feature isn’t recognized. No permanent fix found yet—consider registry edits, permission resets, or rebuilding the service registration. Let me know if you want guidance on those steps.

Have you executed DISM /Online /Cleanup-Image /RestoreHealth? There are also references suggesting a possible corrupted SysprepProvider.dll. The safest approach is to obtain it from a functioning Windows installation, though downloading from sources like DLLMe carries risks—make sure to verify its safety using VirusTotal before use.
