What network discovery and file sharing settings should I check on the Windows 11 machine?

On the Windows 11 machine, go to 'Network and Sharing Center' (search for it in the Start menu). Click 'Change advanced sharing settings'. Ensure 'Turn on network discovery' and 'Turn on file and printer sharing' are selected for the network profile you're using (Private or Public). Also, under 'All Networks', ensure 'Turn off password protected sharing' is selected for easier access, though this reduces security.
