Problems with RDP connectivity

Hello, since I couple of days, I am having severe problems connecting to windows boxes on Academy using Remote Desktop Protocol. The problem started during the Windows Privilege Escalation Module and is also happening with “Shells and Payloads”.

I have tried the 3 major RDP clients, rdesktop xfreerdp & reminna. VPN connection was renewed and resetted a couple of times.

However, these problems are also occurring inside the Parrot-pwnbox, it is therefore not related to my local Kali installation. Is anyone here who is currently having similar issues?

I am again stuck with exactly the same problem in module “Active Directory Enumeration and Attacks”.
I cannot RDP into the MS01 box, the given credentials are refused. The problem is independent of using my personal Kali Machine or HTB Pwnbox.

HTB support suggested to renew my VPN connection which of course did not improve anything. I am stuck with this situation for almost one week. Any idea what could be the issue here?

When I connect to a Windows machine with xfreerdp, it takes less than 10 seconds to connect.
Is there a solution?

I had the same problems and found that it ran better at certain times. I suspect that we share the academy computer with others. There is a maximum number of connections allowed!

At least that is my guess!

Yes, sometimes I realize Pwnbox would get slower and slower. There are some time-dependent resource bottlenecks in the infrastructure.

Changing VPN to a different region is the only thing that helps in this situation.

So I had a similar problem - particularly when the password had special characters, and I was attempting to use xfreerdp.

When the password was something like

AnotherC0mpl3xP4$$

it must be encompassed in single quotes.

I don’t know if this is obvious to others - thought I’d share in case it saves others a heap of time.

If the problem occurs with both Windows and Parrot-pwnbox, then I think this may indicate a problem on the HTB Academy side
Try contacting the HTB Academy support service. They will be able to diagnose your problem. They usually have a support team that can help with technical questions like this. Apart from this, you can also try other connection methods or check for updates for your RDP clients.
