An Azure virtual machine (VM) gives you the flexibility of virtualization without having to buy and maintain the physical hardware that runs it. You can compare it with a laptop on loan in the cloud. The myDRE platform supports Windows VMs (Windows Server 2022; Server 2025) and Linux VMs (Ubuntu 22, Ubuntu 24). This article describes how you can start, connect to and stop Windows VMs. There are two ways of connecting to a Windows VM: Azure Bastion and local RDP (if allowed by your organisation).
Your Workspace may include one or multiple Windows VMs. You can connect to Windows VMs with two concurrent users. When you connect with more, you won't be allowed in and will receive a Bastion related connectivity error.
Within the Windows VMs, the Workspace's data fileshare (Z:) and Inbox (I:) are by default visible from the VM.
How to start, connect to and stop a Windows VM (via Azure Bastion)
- Enter your Workspace by clicking anywhere on the Workspace tile (for example on the arrow).
- Windows VMs display the characteristic Windows logo. Moreover, details such as the template, VM type including cores and RAM and the shutdown time are displayed. More details and actions can be found under the three dots. Be aware that these actions might differ depending on your role in the Workspace.
- If the VM is off, it has the status Deallocated.
- To turn the VM on, click on the purple Start button. The Start button will be faded green and indicate Starting..., while the status indicator Deallocated changes to In progress. This can take up to 30 seconds.
- The VM is on when the status indicator indicates Running. The Start button has changed to an orange Stop button and a green Connect button is displayed.
Depending on your organisational configurations your VM might only display a Private IP instead of Public IP. In this case, connection to the VM is only possible via Bastion.
- Click on the arrow next to the Connect button and you will be forwarded to the Azure portal to connect through Bastion.
- This button will take you to the Azure Portal. Unfortunately, at the time of writing, we are unable to provide a more direct way to use Azure Bastion until Microsoft makes this available.
- The Azure Portal might ask you to authenticate. Log in with your @mydre.org credentials.
- Log in with your @mydre.org credentials and tick the box Open in new browser tab. Make sure that your browser allows this if it is not set by default. Click on Connect.
- A new tab in your browser will open with connection to the desktop of your VM.
- Once you are done with your work, you can press the Windows logo/start menu on the bottom left and click on the power button > Disconnect.
- If the VM is not going to be used for some time by you or someone else, you can stop the VM by clicking on the orange Stop button. The VM is off when the status is on Deallocated. Remember: VMs are pay-as-you-go, so cost-wise it is a good decision to stop the VM if not in use.

A maximum of two concurrent workspace members can connect to the same VM concurrently.
If a third person tries to connect, they will receive the following error message while logging in:
"The target machine has denied access to this connection. If you require access, please grant access to your account on the target machine, or check your system settings."

Concurrent users share the same resources, e.g. performance is better with fewer concurrent users.
A Workspace can host a total of 11 VMs. If you require more than 11 VMs please contact us.
How to start, connect to and stop a Windows VM (via RDP)
These instructions assume you are using a Windows computer. If not, you need to ensure that you can open .rdp-files:
- MacOS: Download and install Microsoft Remote Desktop for free from the App Store. Next, make sure this program is always used to open .rdp files.
- Linux: Make sure you have the latest version of Remmina installed.
- Android: Download and install Microsoft Remote Desktop from the play store.
Some organisations do not allow traffic over port 3389, which is necessary for RDP connections. These organisations might opt for using Microsoft Azure Bastion which allows RDP-over-https (opening the VM in a browser tab) without the necessity of having port 3389 open. For more information, please contact your local Support Team member via a ticket. If you want to connect to a Windows VM via Bastion, skip to the How to start, connect to and stop a Windows VM (via Azure Bastion) section.
