Description of the problem: I am not able to connect through Remote Desktop
Connection to access Computer A from Computer B. More specifically, when I am on Computer B, I am not able to access Computer A through Remote Desktop Connection. I was asked to provide
username and password, but I kept getting told by a "Windows Security" window
that said: "Your credentials n'a pas fonctionné."
Observation 1: J'ai pu access Computer B from Computer A. (The other way
around.)
Observation 2: The only difference as I can tell, is that: J'ai utilisé a Microsoft
Account to log-in (locally and natively) on Computer B, and used a username
alone to log-in on Computer A. The usernames on the two computers (locally
speaking) are:
-
Computer A: DESKTOP-XXX/username
-
Computer B: username@hotmail.com
Both computers are running Windows 10 Pro.
Observation 3: J'ai made sure that the there is no firewall
between the two computers. (They are connected through a Ethernet switch in my
home network, connecting to the outside world through the home router.)
Question: what has been going wrong? Do J'ai to assign and use the same
Microsoft Account on Computer A? J'ai made sure that the password has been
correct all the times, but le problème est persistent: I cannot connect from
Computer B to Computer A, yet I can connect from Computer A to Computer B.
PS: I has also asked the same question in the TechNet forum, yet I am not counting
on it quite a lot. Ref url.
Additional Information
The address for Computer A and B
As I only have dynamic IP on both machines, J'ai utilisé No-IP's service. Thus, for the two computers, par exemple:
- Address for Computer A: computer-A.ddns.net
- Address for Computer B: computer-B.ddns.net
Additional Experiments
Shutting down Computer B
Quand je shut down Computer B, using the address computer-B.ddns.net to connect still gets me the same error message (as in the screenshot above).
Getting a different IP for Computer B
Per the initial experiment, two computers are hosted in the same home network. Thus, the public IP for the two machines should be the same. To get Computer B a different IP, I disconnect the machine from the home network and used the Personal Hotspot on my phone. This time, I get a new error message:
