Azure Virtual Machine is not accessible through RDP or any other mode

Question

Azure Virtual Machine is not accessible through RDP or any other mode

Sivakumaran R 0

I’d appreciate your support in resolving the Azure VM access issue. The VM was working fine earlier, but RDP access suddenly stopped working. In the Azure portal, the Virtual Machine Agent status shows as Not Ready. As recommended by Microsoft troubleshooting guidelines, I’ve already tried the suggested recovery steps, but none of them resolved the issue.

Hello Sivakumaran R,

To know more understand about the issue. Could you please provide the below details.

When did the RDP issue start, and was the VM working fine just before that?

Have there been any recent changes to the VM, such as OS updates, configuration changes, or resizing?

Can you confirm if the VM Agent has always been “Not Ready,” or did it change recently?

Have you tried accessing the VM using the Serial Console?

Has the VM been stopped or deallocated for a long time before this issue occurred?

Did you attempt redeploying the VM or restarting the VM Agent services? If yes, what was the result?

Are there any error messages or logs from boot diagnostics or the VM Agent that you can share?

Please provide please check the boot diagnostic screenshot?

Could you please check the private message and provide the necessary details for further investigation.

To resolve the issue of your Azure Virtual Machine (VM) being inaccessible through RDP and the VM Agent status showing as Not Ready, you can follow these troubleshooting steps:

Check if the VM is Started: Ensure that your VM is running. You can verify this in the Azure portal under the Overview section of your VM.
Verify Guest Agent Status: Go to the Properties tab of your VM in the Azure portal. If the Guest Agent status is Not Ready, it may not be installed or functioning correctly. You might need to reinstall the Guest Agent if it is not operational.
Check Guest Agent Services: If you can connect via RDP, check if the Guest Agent services are running. If not, you may need to start them manually.
Network Security Group (NSG) Rules: Ensure that the NSG associated with your VM allows inbound traffic on TCP port 3389, which is used for RDP. Check for any deny rules that might be blocking access.
Use Serial Console: If RDP is not working, use the Azure Serial Console to troubleshoot further. You can check the status of the Remote Desktop Services and ensure they are running.
Reattach or Replace NIC: Sometimes, the Network Interface Card (NIC) may stop responding. Consider detaching the current NIC and attaching a new one to the VM.
Recreate RDP Listener: If the RDP listener is misconfigured, you may need to recreate it via the registry settings.
Redeploy the VM: As a last resort, if none of the above steps work, consider redeploying your VM to restore its functionality.

By following these steps, you should be able to diagnose and potentially resolve the access issue with your Azure VM.
