Windows 11 PCs intermittently lose mapped drives and default printers

[Jack.G]

I manage a small office network of about twenty Windows 11 machines, and we've been plagued by a persistent issue where several computers randomly lose their network drive mappings and default printer settings, requiring a manual reboot to restore connectivity, which is disrupting productivity daily. I've tried the basic Windows troubleshooting steps like running the network troubleshooter, checking group policy, and updating drivers, but the problem recurs inconsistently across different users, making it difficult to isolate a root cause. For other IT admins, what deeper diagnostic tools or logs within Windows should I be examining to track down this kind of intermittent network resource issue? Have you encountered similar problems tied to specific Windows updates, power settings, or credential manager quirks, and what was your definitive fix?
