Windows 10 Network Shares: Fixing a Connection Failure

This applies to an older Windows 10 build-era issue; kept here for reference if you’re troubleshooting a similar symptom on a legacy system. If you’re signed into Windows 10 with a Microsoft account and add a PIN for faster sign-in, some users found this broke their ability to reach network shares or print to network printers — despite everything having worked fine with just a password.

Why This Happens

This traces back to how Windows handles credentials for network resources when a PIN is in use — the PIN itself is device-local and isn’t directly usable as network authentication, so if Windows can’t correctly fall back to your account’s actual network credentials, share and printer access can fail even though local sign-in works fine.

What to Try

• Store explicit credentials for the network share/printer via Control Panel > Credential Manager > Windows Credentials, adding the target server and your full account credentials directly, so Windows doesn’t need to derive them from the PIN sign-in.
• Check Settings > Accounts > Sign-in options for any additional Windows Hello/PIN-related settings affecting network credential behaviour, since this area has changed across Windows 10 feature updates.
• As a fallback, removing the PIN and reverting to password sign-in confirms whether the PIN is definitely the cause before spending more time on it.

Still the Right Tool on Current Windows (Updated for 2026)

Credential Manager (Control Panel > Credential Manager > Windows Credentials) remains the correct place to store explicit network credentials on current Windows 10/11 when a PIN or Windows Hello sign-in is getting in the way of network authentication — nothing about this mechanism has changed. As the note above says, this is a legacy-build-era symptom; if you’re troubleshooting something that looks similar on a fully current system, it’s worth double-checking you’re not looking at an unrelated cause before assuming this is the same issue.
