Not able to RDP on a EC2 instance

Question

I am trying to RDP into an EC2 instance from my windows 7 machine however always gets

Remote Desktop Can't Connect to remote Comupter for one of these resons

1.) Remote Desktop to server is not enabled

2.) The remote Computer is turnnned off

3.) The remote computer is not avilable on the network.

I am able to RDP other EC2 instance. also a as work-around I am able to RDP into the subjected instance from other EC2 machine but not from my windows 7 machine and also other machine on the network.

Checked the security GROUP of both RDP-working and RDP-non-working ec2 instance and they are configured identical (port 3389 enabled).

Any suggestion please!!!!

Answer 1

1. In the AWS console, edit your security group or create a new one and add a new Inbound rule: "All Traffic" and Custom IP = {Your IP}

2. Go to the instance you want to connect to and press Connect and download the Remote Desktop File or open it from the web browser.

3. In the same screen as in point 2 (Connect to your instance), click on Get Password and uploaded your .pem file directory that you should have downloaded earlier and decrypt my password

4. Sign into the RDP using Administrator for the username and that password.

It's important to note that your default security group in AWS does not allow RDPing, which is why step 1 is important here.

Answer 2

I hope you have already tried and tested all the above suggestions like-

1. Verifying whether your instance have the RDP protocol step correctly or not.
2. Added a new inbound rule i.e. a Custom TCP port(i.e. 3389) in your security group.

If you still have the issue, the one thing you can try is to check you xrdp.ini file (for ubuntu it is located at /etc/xrdp/xrdp.ini) should contain the port field as port=ask-1 if it contains any other value( for example port=askaskaskask-1 that means you had run the setup commands more than once) change it to port=ask-1.

Answer 3

Before connecting through RDP you need to create an Inbound Rule type RDP (TCP on Port 3389) on "Security Groups". You can either add it to the existing security group or create a new group, BUT if you create a new security group you must go to "Network Interfaces", select the interface, go to Actions > Change Security Group and include the new group.

Answer 4

I have also faced the same problem. Please follow the steps

Open the RDP port (3389) in AWS instance security group inbound rules.

• For windows- Check RDP port is opened or not in the local system windows firewall. If not opened, please open it.

• For Linux - Allow the RDP port in the Linux server as well. Use the following command.

  sudo ufw allow 3389/tcp
