Issue: Not able to connect Azure Windows Server to RDP

Solution: Once connected to the server's console, try to uninstall the third-party firewall software using its uninstallation method. This could be through the Control Panel's "Programs and Features" or by running the software's uninstaller if it provides one.

I'm sorry to hear that you're experiencing issues connecting to your Azure Windows Server. There could be several reasons why you're unable to establish an RDP connection or ping the server. Here are a few troubleshooting steps you can try:

Check the server's network connectivity: Make sure that the server has a stable network connection. Ensure that the network adapter is enabled and properly configured in the Azure portal. You can also try restarting the server to see if it resolves any temporary network issues.

Verify the server's public IP address: Double-check that the server's public IP address is correct and hasn't changed. You can find the IP address in the Azure portal by navigating to the Virtual Machine's Networking settings.

Review the network security group (NSG) rules: NSGs are used to control inbound and outbound traffic to your Azure resources. Ensure that the NSG associated with your server allows incoming Remote Desktop Protocol (RDP) traffic (port 3389) from your IP address or the IP range you're connecting from.

Check the Windows Firewall settings: If you've installed a third-party firewall on the server, it might have altered the Windows Firewall configuration. Make sure that RDP traffic is allowed through the Windows Firewall. You can temporarily disable the firewall to check if it's causing the issue.

Validate the RDP endpoint: Confirm that the Remote Desktop feature is enabled on the server. You can check this in the System Properties of the server. Additionally, ensure that the RDP port (3389) is not blocked by any other software or firewall.

Restart the server: Sometimes, a simple server restart can resolve connectivity issues. You can restart the server from the Azure portal or by using the Azure PowerShell or Azure CLI.

Review event logs and diagnostic information: If the above steps don't resolve the issue, you can check the server's event logs and diagnostic information for any error messages or clues about the problem. This information can help you pinpoint the underlying cause.

If none of these steps help, I would recommend reaching out to Azure support for further assistance. They will be able to analyze your specific configuration and provide more targeted guidance.

Remember to always exercise caution when modifying server configurations and installing third-party software to avoid potential issues in the future.

Hi Priscilla, thanks for replying. We have tried installing the third party software for firewall and after that its not working. Is there any way i can override the changes/remove the software so that my windows server can be regained to the older state.
