How to Fix: Error when trying to copy over the network using robocopy

Error when trying to copy over the network using robocopy, unable to find network name.

Quick Answer: Check your network settings and ensure the network name is correctly configured in the Robocopy command.

Error when trying to copy over the network using robocopy occurs when the network name cannot be found, preventing the file transfer process from completing successfully. This issue affects users who are attempting to use Robocopy for large-scale file transfers or data migrations across a network.

This error can be frustrating, especially in production environments where timely data transfer is crucial. Fortunately, there are steps that can be taken to resolve this issue and get the file copy process back on track.

🔍 Why This Happens

  • The primary reason for this error is that the network name used in the Robocopy command is not correctly formatted or is not recognized by the system. This could be due to a typo, incorrect casing, or an outdated DNS entry.
  • Another possible cause of this error is that the server or device hosting the destination share is down or unreachable, causing the network name to appear as unavailable.

🚀 How to Resolve This Issue

Resolving Network Name Issues

  1. Step 1: Verify that the network name used in the Robocopy command matches the actual name of the destination share. Ensure that the casing and formatting match exactly, including any domain or workgroup names.
  2. Step 2: Check the DNS settings on both the source and destination machines to ensure they are up-to-date and correctly configured. This may involve checking the host file entries, DNS server addresses, or WINS (Windows Internet Naming Service) settings.
  3. Step 3: If using a workgroup name, verify that it is correctly set in the Windows Registry or Group Policy Editor on both machines.

Alternative: Checking Server and Network Connectivity

  1. Step 1: Ensure that the destination server or device hosting the share is powered on, connected to the network, and has an active internet connection.
  2. Step 2: Verify that the destination share is accessible from other machines on the network using the Robocopy command. If this works, it may indicate a problem with the source machine's connection to the network.

🎯 Final Words

To resolve the error when trying to copy over the network using Robocopy, first verify that the network name used in the command is correct and that DNS settings are up-to-date. As an alternative, check server and network connectivity issues by ensuring the destination server or device is accessible and powered on. By following these steps, you should be able to successfully transfer files across your network using Robocopy.
