 For Windows, **Remote Desktop Connection** from Microsoft can be used. After **Remote Desktop Connection** has been started, a new profile should be created. To do this, first click on "Show options". For Windows, **Remote Desktop Connection** from Microsoft can be used.

-Unfortunately **Remote Desktop Connection** does not support tunneling into the university network via SSH or any other free softwareFrom outside the university network a connection has to be established, e.g., via a SSH tunnelFor this purpose a SSH client like **PuTTY** is recommended. We will not go into further details on how to configure this, since detailed instructions are already available on the Internet (see e.g. [[https://www.saotn.org/tunnel-rdp-through-ssh/|www.saotn.org]]). +However, these settings only work if access is not from the local IP address space. For external access, a tunnel to the university network must first be established. Unfortunately**Remote Desktop Connection** does not directly support an SSH tunnel like **Remina**However, on modern systems this can be easily solved using **PowerShell**. 
 + 
 +=== PowerShell + RDP Client === 
 + 
 +Current installations of Windows 10 and 11 have built-in SSH clientWe can use this to create an SSH tunnel to the network and then connect to the OMS via the RDP client
 + 
 +  - Log in to the University VPN 
 +  - Open **PowerShell** from the Windows Start menu 
 +  - Type or copy the following command into **PowerShell** and use it to create the SSH tunnel: <code>ssh -N -L 3399:IP_of_the_OMS.39:3389 pollux@columba.astro.physik.uni-potsdam.de</code> 
 +  - Launch the RDP client from the Windows Start menu and enter //BP34_Admin// as the ''User name'' and //localhost:3399// as the ''Computer''
 +  - Press Enter and enter the password 
 +  - Done :) 
 + 
 +=== Alternative to the RDP client from Microsoft - MobaXterm === 
 + 
 +Alternatively, [[http://mobaxterm.mobatek.net/|MobaXterm]] can be used under Windows. Via [[http://mobaxterm.mobatek.net/|MobaXterm]], in contrast to the RDP client of Windows, an SSH tunnel can be established, which is called "SSH jump host". First of all a new session has to be established and for this the **RDP** protocol has to be selected. Click **RDP** and make the basic settings. As **Remote host** the IP of the OMS has to be specified, which will be disclosed on request. As **username** you have to enter ''BP34_User'' again.

 +In the second step, the tab **Network settings** must be selectedThere you have to click on **SSH gateway (jump host)** to specify the SSH hostDon't be surprised there are no changes shown in this window, after the next step. 
 + 
 +In the window that opens, the **Gateway host** must be specified. In the example shown here we used ''columba'' but basically any host from the Astro domain can be used for this. The **Username** has to be chosen accordingly.  
 + 
 +By clicking **OK** the settings of the corresponding windows can be confirmed. Afterwards the connection can be established.
