I'm having issues connecting to an old Virtual Machine via Remote Desktop Connection. Need support please.

Hi Tristain,

There could be different reasons and for this you will need to troubleshoot using the link I have shared - https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/troubleshoot-rdp-connection

Could be NSG blocking or RDP not enabled? Any Firewall or ports might be getting block so check the guidance please.

Hope this helps.

Hi @Tristan Reid ,

Thank you for reporting the issue in Q/A. I understand that you’re facing trouble connecting to your VM. To help resolve this, please try the following steps:

First, try connecting to the Azure Serial Console from the Azure portal. This allows you to check if the VM itself is accessible even when RDP is not working.

Reference: https://learn.microsoft.com/en-us/troubleshoot/azure/virtual-machines/windows/serial-console-overview

Make sure the Network Security Group (NSG) allows inbound traffic on port 3389 (RDP), and check that the Windows Firewall on the VM isn’t blocking RDP.

If RDP still does not work, use Azure Network Watcher – Connection Troubleshoot to test connectivity from another VM or network resource. This helps identify if traffic is being blocked.

Reference: https://learn.microsoft.com/en-us/azure/network-watcher/connection-troubleshoot-overview

Also, you can also check the Boot Diagnostics to see if the VM has started successfully.

Reference: https://learn.microsoft.com/en-us/azure/virtual-machines/boot-diagnostics

You can reset the RDP configuration on the VM using the Azure portal or command line, which can help restore the necessary settings.

As mentioned in the below documentation, If the issue persists, you can restart or redeploy the VM. Redeploying moves the VM to a new Azure node while keeping most settings and data intact.

When you redeploy an Azure VM, it gets moved to a new node, but it keeps its settings and most of your data intact. changes happen when you re-deploy

• What remains unchanged: Your OS disk and any attached data disks will stay intact, along with all system configurations, network settings, security rules, and installed applications. You won’t lose any data stored on these persistent disks.
• What gets lost: Any data stored on the temporary disk (D: in Windows VMs) will be deleted, ephemeral disks will be wiped, and your dynamic IP address may change. If you have important files on the temporary disk, it’s best to back them up before redeploying Redeploy Windows virtual machine to new Azure node

Note: Before performing any activity, please make sure backup of your things to void data loss

Hope this helps! please let me know if you have any queries.
