Many users get the error message “An error occurred while updating the Ethernet interface” when using the IP Config command at the Windows command prompt (Command Prompt and PowerShell). The second part of the error message may contain the following message:
- Access to the Ethernet network is denied.
- Unable to contact your DHCP server
- The name specified in the network management block is used on the remote adapter.
- An attempt was made to access a socket
- RPC server is unavailable
- Object already exists
- Data is not valid
- A DHCP client has obtained an IP address that is already in use on this network.
- The operation was canceled by a user.
What causes the message “An error occurred while updating the Ethernet interface” in Windows 10?
DHCP client service is disabled: Another possible reason for this error is that the DHCP client service was disabled due to manual intervention by the user or optimization analysis by a third-party management tool. If this is the case, you can solve the problem by re-enabling the DHCP Client service on the Services tab and changing the default startup type.
Outdated/incompatible network card driver: If this problem occurs after upgrading from an older version of Windows (Windows 7 or Windows 8.1) to Windows 10, it is most likely due to a partially incompatible network card driver. In this case, you can solve the problem by updating your network adapter to the latest version available through Device Manager.
Common network card problem: If the problem is related to a common network card problem, you can solve the problem by running the network card troubleshooter and applying the recommended solution.
Quick Launch Conflict: It turns out that some network adapter drivers may have a conflict between the Quick Launch feature and Windows 10. If you do not want to replace the current driver, the only solution to this problem is to disable the quick start feature through the Power Options menu.
TCP/IP mismatch: In most documented cases, this problem is due to incorrect caching of temporary IP and TCP data which cannot be erased in the traditional way. If this scenario applies, you should first do a full Winsock reset and see if you can run the ipconfg commands again.
System file mismatch: In some circumstances, you can expect this error if some of your system files used when the operating system needs to execute terminal commands are affected by corrupt system files. In this case, you should update all Windows files using procedures such as Clean Install or Repair Install to resolve the problem.
Network mismatch: According to several concerned users, this problem is often related to a network problem, indirectly caused by your router’s built-in firewall or some other type of system-level restriction. In this case, a simple factory reset of the router is a possible solution.
