Connect to Windows VM via RDP#

This guide shows you how to connect to a Windows Server virtual machine (VM) on the myDelska platform using the Remote Desktop Protocol (RDP) from Windows, macOS, or Linux.

Prerequisites#

• A deployed VM running Windows Server — see First VM Deployment.
• The VM’s public IP address — find it in the Dashboard, or connect over a private network/VPN.
• The Administrator password set during deployment or in the VM Settings.
• A firewall rule allowing inbound TCP port 3389 (see the security note below).

Security note: Do not open port 3389 to the whole Internet. Create an inbound firewall rule that allows TCP 3389 only from your own IP address or network. For stronger protection, keep the VM on a private network and connect through a VPN.

How to connect from Windows#

1. Press Windows + R, type mstsc, and press Enter to open Remote Desktop Connection.
2. In the Computer field, enter the VM’s public IP address.
3. Click Show Options and enter the username (Administrator by default).
4. Click Connect and enter the password.
5. If a certificate warning appears on the first connection, review it and click Yes to continue.

You should now see the Windows Server desktop of your VM.

How to connect from macOS#

1. Install the free Windows App (formerly Microsoft Remote Desktop) from the App Store.
2. Click + » Add PC and enter the VM’s public IP address.
3. Add a user account (Administrator and your password), or leave it to be asked every time.
4. Double-click the saved PC to connect.

How to connect from Linux#

Use an RDP client such as Remmina (preinstalled on many distributions) or FreeRDP:

xfreerdp /v:<public_IP_address_of_VM> /u:Administrator /p:'<password>' /dynamic-resolution

Expected result#

After authenticating, you get a full Windows desktop session on your VM. You can now manage the server, install software, and configure services.

Troubleshooting#

• Connection timed out — check that an inbound firewall rule allows TCP 3389 from your IP, and that the VM is running.
• Wrong credentials — reset the password in the VM Settings section.
• “An authentication error has occurred… encryption oracle remediation” (CredSSP) — the client and the server have mismatched security updates. Install Windows updates on your local computer and on the VM, then reconnect.
• “An internal error has occurred” — usually stale RDP sessions or a TLS mismatch. Restart the VM (or the Remote Desktop Services service via the VNC Console) and try again.
• RDP is not available at all — use the VNC Console to access the VM and check the Remote Desktop settings inside Windows (Remote Desktop must be enabled, and the user must be allowed to connect).

More common issues are covered in the Troubleshooting guide.

Next steps#

• Activate your Windows Server license
• Add extra disk storage
• Set up backups for your VM

Open in myDelska Platform#

Log in to myDelska and open Dashboard » Instances in your Workspace (/workspace/{workspaceId}/dashboard/instances) to find your VM’s public IP address and manage its settings.
