Access to Amazon EC2 Windows instance via Remote Desktop

Question

I'm new to AWS EC2 and I'm trying to access to a windows instance (it's an image created from another instance),

But when I click on Get password in RDP section, i got this message:

The instance was running since yesterday so why I still have this message? is this something related to missing configuration?

Thanks for your help!

Answer 1

Check the console output for the instance to see whether the AMI that you used to launch it was created with password generation disabled. If password generation is disabled, the console output contains the following:

Ec2SetPassword: Disabled

If password generation is disabled and you don't remember the password for the original instance, you can reset the password for this instance. For more information, see. Reset a lost or expired Windows administrator password
