Windows EC2 connectivity issues
I accidentally disabled network connectivity in Windows while I was working on it, and I’ve lost connection to my Amazon EC2 instance. How can I fix it?
You can create a temporary Elastic Network Interface (ENI) and attach it to your instance. This will allow you to connect to the instance temporarily and fix the issue.
- Sign in to the Amazon EC2 management console.
- Select your instance, and make a note of what subnet its ENI is in.
- Create a new ENI in the same subnet as the instance, selecting a security group that allows you to connect to your instance via RDP.
- Attach the new ENI to your instance.
Note: The new ENI might take a few minutes to come online. If you connect to the instance over the Internet via RDP, associate an Elastic IP address with the ENI. - Make sure that the security group associated with your instance allows inbound RDP connections.
- Using the new ENI, connect to your instance using RDP.
- Change the network connection settings in Windows to use DHCP, or specify the correct private IP address settings.
- Detach the temporary ENI.
Note: If you’ve associated an Elastic IP address with the ENI, and no longer need the Elastic IP address, release it by following the instructions at Releasing an Elastic IP Address.
