<div>
from powershell you could do this:<br />

<pre><code class="code-1 nolinks" id="code-20-43312587-1"><span>Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp' -name &quot;PortNumber&quot; -Value 3389</span>
</code></pre>
<br />
<br />

<br />
I checked my terminal server and it doesn't have anything in there - EG: I think if there's no value it'll default to 3389.<br />
<br />
So from SSH I would recommend deleting the key by running:<br />

<pre><code class="code-1 nolinks" id="code-20-43312587-2"><span>reg delete &quot;HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber&quot;</span>
</code></pre>
<br />
worse comes to worse you can add it back with:<br />

<pre><code class="code-1 nolinks" id="code-20-43312587-3"><span>reg add &quot;HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp&quot; /v PortNumber /t reg_dword /d 3389&quot;</span>
</code></pre>

if you ssh into your system what do you get? &nbsp;a command prompt? <br />
<br />
when you changed the port dis you also change the windows firewall to allow that port? Same with the hosting companies firewall?

Hello&nbsp;<a href="https://www.experts-exchange.com/members/ve3ofa.html" rel="ugc">David Johnson, CD</a>&nbsp;<br>Thanks for your reponse;<br><br>Unfortunately i did not think about firewall when i changed the port and i had to.<br><br>I use Putty to ssh in my system; so it a command line window.

<div>
More details:<br>When i contacted my hosting company; they suggested that i use rescue mode: Linux/BSD.<br><br>So maybe what i search for is Linux commands. <br><br>My Server is: Windows Server 2008

I edited my above comment in case anyone else came across the thread. &nbsp;Note to refresh your commands if you copied them as RDP-TCP is it's own folder underneath winStations.<br />
<br />
Command should have been: &nbsp;<br />

<pre><code class="code-1 nolinks" id="code-20-43312681-1"><span>reg delete &quot;HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber&quot;</span>
<span></span>
<span>reg add &quot;HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-TCP&quot; /v PortNumber /t reg_dword /d 3389&quot;</span>
</code></pre>
<br />
given that you're using a bash shell you need to connect to the server from there. &nbsp;Can you ssh to the actual server?
</div>


<div>
Thanks&nbsp;<a href="https://www.experts-exchange.com/members/ged325.html" rel="ugc">Kyle Abrahams</a>&nbsp;<br><br>I think your command works in case of ssh over Windows System ( not sure)<br><br>My case may be a little different; I have a BSD/Linux launched over network on Windows server.<br>So I think i need the same command which you sent may for Linux.<br><br>I really appreciate any information which can help.<br><br>regards.&nbsp;

<div>
How are you connecting to your RDP system? &nbsp;Through a VPN? &nbsp;Through a jump server?<br><br>When you RDP and use a different port, you can use the hostname or IP address followed by a colon, then the port number.<br><br><strong>MYRDP_Server:3341</strong><br><br>or<br><br><strong>192.168.1.55:3341</strong><br><br>If you've changed the port, but didn't update your port forwarding at your firewall, it won't work. &nbsp;You will need to get to a internal system and connect.

Hi Serialband;<br><br>infortunately, i've changed the port without updating port forwarding.<br><br>My hosting company ( OVH) launched à BSD/Linux over network on my server. I find this strange to use linux on Windows but i am not expert.<br><br>So, when i searched for solution, i found that if i can run Windows command, it will be easy using powershell;<br><br>and also&nbsp;<a href="https://www.experts-exchange.com/members/ged325.html" rel="ugc">Kyle Abrahams</a> mentionned how to use CMD (I think ) to delete and add port number.<br><br>The problem that i am not in windows environment.<br><br>So I searched for my situation case; i found a linux tool chntpw; but is not clear how to use it; i found some tutorials, but they did not work.<br>also there is a command available on ssh ( reged ) but the same situation, not clear how to use it.

It might be easier to see if you can run a port forward in Linux to redirect your port back to 3389 and then connect to Windows to correct it. &nbsp;You can also just leave it that way and use the ssh port forward as an additional gateway. &nbsp;You don't want port 3389 open to the internet, since you be experiencing a constant barrage of brute force attempts by script kiddies the moment it's been detected.<br><br>ssh -L &lt;localport&gt;:&lt;remotehost&gt;:&lt;remoteport&gt; &lt;yourID&gt;@yourbastionhost<br><br>ssh -L &lt;3389&gt;:&lt;windowshost&gt;:&lt;3341&gt; &lt;yourID&gt;@yourbastionhost<br><br>

I would to Thank you all;<br><br>I used VNC connection to login to my server, then i used cmd to copy registry file from C:\Windows\System32\config\RegBack to C:\Windows\System32\config<br><br>Reboot and that worked.<br><br>Thanks.<br><br>Best regards
