Troubleshoot Remote Desktop connections to an Azure virtual machine

• Reset Remote Desktop configuration & Password .
• Check Network Security Group rules / Cloud Services endpoints.
• Review VM console logs.
• Reset the NIC for the VM.
• Check the VM Resource Health.
• Reset your VM password.

Troubleshoot Azure Vms:

Scenario-1 : When user has forgot the Azure VM  local administrator password   and if something went on the Azure Remote Desktop Connection then we will use the below solution.

1: Reset your RDP connection & Passwords. This troubleshooting step resets the RDP configuration when Remote Connections are disabled or Windows Firewall rules are blocking RDP.

Reset the Remote Desktop service configuration & Password .

• Select drop down Menu then select the reset configuration only  to reset the remote configuration of The VMS.
• Click Update and It will apply as per your selected services.

Scenario-2:- If we are unable to connect to Azure using RDP then there might be chances that it is blocking by the NSG or Azure Endpoint is not allowing the RDP . So we have make an exception in NSG/Endpoint rule to allow RDP access.

 

Step2: Check the Network Security Group/Cloud Services Endpoints in Classic Mode (ASM)

• Logging to Azure Portal: – https:// Portal.azure.com

Select the NSG Group and click on Edit if required.

• GO to Settings and click on the inbound NSG security Rule.
• Select the Inbound Security Rule

Scenario-3: VM resource health will be useful on when something is went wrong form Azure data center or your VM got corrupted . So it will tell the health of your Azure VMs or services.

Step -3: Check the VM Resource Health.

This troubleshooting step verifies there are no known issues with the Azure platform that may impact connectivity to the VM.

Select your VM in the Azure portal. Scroll down the settings pane to the Support + Troubleshooting section near bottom of the list. Click the Resource Health button. A healthy VM reports as being Available.

You can try troubleshoot Tool for more troubleshooting of Vms.

Scenario 4: Suppose you have made the some changes on your VMs like (Winodws update, Network settings configuration, software installation ) or any other changes which cause the remote desktop connectivity loss . Then we can reboot the server .

Most of the common scenario reboot will fix the issue.

Step:4- Restart your VM. This troubleshooting step can correct any underlying issues the VM itself is having.

Select your VM in the Azure portal and click the Overview Tab. Click the Restart button:

Most of the issue are resolved by Restarting the VM but make sure you will reboot the vm during the non-business Hours.

Step-5 Diagnostics settings: Please enable the diagnostic settings to understand what is issue is there in VM.

Please enable the Diagnostic setting so it will collect all the logs and it will be easy to understand the issue

Once you will configure the DIagnostic Setting , You will be able to configure the logs,Performance counter , Crash Dumps ,Dinks  and Agent Status.

Please go head and click Each tab and try to understand the troubleshooting scenario and configure the logs as per your Project/Customer requirements. 

 

Step 6: Re-deploy the VM:  You can use this scenario only if no solution will work , then it will help you get new VM instance with Same image , Data and application configuration.

Note: Redeploying your virtual machine, which will migrate it to a new Azure host. If you continue, the virtual machine will be restarted and you will lose any data on the temporary drive (which is created with Azure VM image). While the redeployment is in progress, the virtual machine will be unavailable.

Production Data and application will not harm while performing this steps.
