Fix the Network Credentials Error in Windows File Sharing
Source-checked About 10 minutes
Answer
Confirm both PCs use the same private network, share the intended folder with an authorized account, and enter that computer's current username and password.
Check the starting state
Before changing Windows network credentials, identify the host PC and share, confirm a trusted private network, record the authorized host account, and test access by UNC path. Keep the current state, exact message, and any recent change available so each result can be compared.
Choose the supported path
Share with the minimum named-user permission and enter the host computer's current username and password; do not enable insecure guest access or SMB 1.0.
Check the network profile
Connect both PCs to the trusted network and set the connection to Private only when you trust it.
Enable sharing
Turn on Network discovery and File and printer sharing for private networks.
Share with a specific account
In the folder's sharing settings, grant only the required account and permission level.
Enter the host credentials
Use an account and current password from the PC hosting the folder. Remove stale saved credentials only when you know the replacement.
Verify the result
the authorized user reconnects after sign-out and can perform only the intended read or write action. Repeat the original task once more after reopening the relevant app, connection, or Windows session so a temporary result is not mistaken for a fix.
Troubleshoot Windows network credentials
If credentials are organization-managed, the host cannot be reached, permissions exceed the intended scope, or access works only with insecure guest settings, stop broad resets and return to the last known state. Preserve the exact error, versions, device or account scope, and failed step before using the linked official support channel.
