The 'Network error: The specified network name is no longer available' message appears when you're unable to connect to a network share on your Win Server 2003 SP2. This issue affects users who are trying to access files or move them from a shared folder on the server.

This error can be frustrating, especially if you were in the middle of an operation and suddenly receive this message. However, don't worry; we'll walk through some steps to resolve this problem.

💡 Why You Are Getting This Error

  • The primary reason for this error is that the network share has been removed or deleted from the server. This can happen due to various reasons such as network configuration changes, server maintenance, or accidental deletion. Another possible cause could be a misconfigured DNS entry or a faulty network adapter.

🚀 How to Resolve This Issue

Restarting the Server and Re-adding Network Share

  1. Step 1: Step 1: Restart the server to ensure all services have been fully shut down. This will help resolve any temporary connection issues.
  2. Step 2: Step 2: Log in to the server as an administrator and navigate to the 'Network and Sharing Center' (you can do this by clicking on Start, Control Panel, Network and Internet, Network and Sharing Center).
  3. Step 3: Step 3: Click on 'Change adapter settings' and select the network connection that is currently connected to the server. Right-click on it and select 'Properties'.
  4. Step 4: Step 4: In the Properties window, ensure that the 'Internet Protocol Version 4 (TCP/IPv4)' or 'Internet Protocol Version 6 (TCP/IPv6)' is set to obtain an IP address automatically. Click 'OK' to save these changes.
  5. Step 5: Step 5: Now, navigate back to the Network and Sharing Center and click on 'Change advanced sharing settings'.
  6. Step 6: Step 6: Under 'Network discovery', select 'Turn on network discovery'. Click 'OK' to apply these changes.
  7. Step 7: Step 7: Navigate to the folder that you were trying to access earlier. Right-click on it and select 'Map network drive...'. Enter the UNC path of the shared folder, including the server name, and click 'Finish'.

  2. Step 2: Step 2: In the Command Prompt, run the command `net use z: \server oldername` (replace '\server oldername' with the UNC path of the shared folder). Replace 'z:' with the drive letter you want to map the network share to.
  3. Step 3: Step 3: If prompted for a username and password, enter the credentials of the user account that has access to the shared folder. Press Enter to log in.
  4. Step 4: Step 4: Once logged in, navigate back to the Command Prompt and run the command `net use z: /delete` (replace 'z:' with the drive letter you mapped earlier).
