Remote Desktop Connection not working for one EC2 Instance
« on: June 14, 2020, 05:31:10 PM »
Hi
I realize this is not a NetTalk request for help, but......

Im using  Amazon EC2 Micros to host my software for different clients- one EC2 Instance per client.
Depending on version, some are secure connections within the nettalk app and others not.

The Clients and I all access their individual  EC2 desktops using Remote Desktop Connection( RDP)
All IP addresses are not elastic.

My current issue is that I can connect to all Instance desktops using RDP except one

My Routine is 
When opening RDP  the IP address of the Amazon server is entered
and on "Connect" The Instance Windows Password is entered
(If I consciously type the wrong password -RDP returns "Login attempt failed"  so I know  the password is apparently, correct
On entering the correct password the window displays the progress bar as normal and it processes to "Configuring remote session"
Doesn't get further than this and cycles back to the home RDP screen

I have checked my Amazon Console and this particular server is running
I have removed my antivirus software, closed the Firewalls and Firefox is my default browser, on Windows 10 PC
I have searched unsuccessfully the Amazon help

Because the client is otherwise active, I dont want to  stop the instance and restart unnecessarily, as the IP address will change...

What to do ???
Thanks
Regards,
Richard

Hi Richard,

Have you setup inbound rules in your security group(s) for RDP?

As RDP is not safe, you normally lock it down to your know client IP, but pretty sure you still need some inbound rule for  port 3389.

Reboot from Inside Actions did the trick and retained the IP address.
Thanks

Hi Richard,

I've seen that happen, once in my AWS. I ended up killing the instance and restarting and it started behaving again.

Regards
Bill
