When net use * /delete fails to clear cached network credentials, you must manually remove the stored entries from Windows Credential Manager. This tool holds onto authentication tokens even after the connection is severed, causing persistent access issues for deleted shares.
Why net use Fails to Clear Credentials
The command-line utilitynet use manages active sessions and maps drives, but it does not always purge the underlying credential store used by the operating system. Windows maintains a separate database of saved passwords in the Credential Manager service. When you delete a mapped drive or disconnect a session, the OS often retains the username and password hash to facilitate faster reconnection next time. This behavior is intentional for user convenience but becomes problematic when you need to force a logout or switch accounts on a shared resource.
If you attempt to reconnect using net use \\server\share /user:newuser and it silently fails or uses old credentials, the issue lies within this hidden cache. The system prioritizes the stored credentials over new input if it believes they are still valid for the current session context. Understanding this distinction between active network sessions and persistent credential storage is crucial for troubleshooting connectivity problems in enterprise environments or when managing multiple user accounts on a single machine.
Accessing Credential Manager
To resolve the issue, you need to interact directly with the Credential Manager interface. You can access this through the Control Panel or by searching for it in the Start menu. Open the Start menu and type "Credential Manager" to launch the application. Alternatively, navigate to Control Panel > User Accounts > Credential Manager. This central hub displays all applications and websites that have saved your login information. Once opened, you will see two main categories: Windows Credentials and Web Credentials. Network shares, mapped drives, and domain authentications are stored under the Windows Credentials section. Select this option to view the list of saved network identities. You may notice entries listed by IP address, server name, or domain controller. These entries represent the cached authentication data thatnet use failed to remove.
Removing Specific Network Entries
Identify the specific entry corresponding to the problematic network share. Look for the target server's IP address or hostname in the list. Click on the arrow next to the entry to expand its details. You will see the Username and Password fields, though the password itself will be masked for security. Click the Remove link at the bottom of the expanded view. A confirmation dialog will appear asking if you are sure you want to remove this item. Confirm the action. Repeat this process for any other related entries associated with the same server or domain. It is important to remove both the IP-based entry and the DNS-name entry if both exist, as Windows might try either one during connection attempts. After removal, close the Credential Manager window. Do not restart the computer yet. Instead, verify if the issue persists by attempting to map the drive again or accessing the share via File Explorer. If the problem remains, proceed to the next step to ensure no residual processes are holding onto the stale token.Clearing the Entire Cache (Optional)
In some cases, individual removal might not be sufficient if multiple services are caching the same credentials. You can choose to clear all Windows Credentials, but this requires re-entering passwords for all saved network resources, including OneDrive, email clients, and other mapped drives. Use this method only if targeted removal fails or if you suspect widespread credential corruption. To do this, click Manage Windows Credentials at the top of the page. Review the list carefully. For each entry, click the dropdown arrow and select Remove. This action is irreversible for those specific items, so ensure you know the passwords required for subsequent logins. After clearing the desired entries, test your network connectivity again. For users experiencing broader system instability unrelated to credentials, such as input device failures, refer to our guide on Windows 10 Enterprise: Keyboard Not Detected in Managed Organization with Admin Privileges. While distinct issues, both require careful manipulation of system settings to restore functionality.Verifying the Fix
Once the credentials are removed, attempt to access the network resource again. Windows should now prompt you for fresh authentication details. Enter the correct username and password. Ensure you check the box for "Remember my credentials" only if you intend to save them again for future use. If you do not wish to save them, leave it unchecked. Successful connection indicates that the stale cache has been cleared. If you still encounter errors, check if the network adapter itself needs to be reset. Sometimes, flushing the DNS cache withipconfig /flushdns helps resolve naming resolution conflicts that mimic credential issues. Additionally, restarting the Workstation service can help clear lingering session states. Right-click the Start button, select Run, type services.msc, find Workstation, right-click, and select Restart.
This comprehensive approach ensures that both the active session and the persistent storage are cleaned up, forcing Windows Explorer to treat the next connection attempt as a fresh authentication request.
Frequently Asked Questions
Does deleting a mapped drive remove the password?
No, disconnecting a drive vianet use only ends the active session. The password remains stored in Credential Manager until explicitly deleted. You must manually remove the entry from the Windows Credentials list to fully forget the password.
Can I use Command Prompt to delete credentials?
Whilecmdkey exists, it is less reliable for general network shares than Credential Manager. Use cmdkey /list to see stored targets and cmdkey /delete:TargetName to remove specific ones. However, the GUI method is more intuitive for identifying the correct server entry.
