Azure VM RDP connection problem

Question

I cannot RDP into my Azure VM ("Remote Desktop can't connect to the remote computer..."). I have added an inbound rule on my security group for RDP with source as Any or using My IP Address.

I also ran the "comprehensive RDP connectivity test” from Azure Connect section, and it says all is good, except that my company firewall may be blocking the RDP connection to this VM.

Answer 1

Hi Fisher John

Make sure there is no blocking inside the VM like Windows Firewall or some antivirus

To make sure it's not a NSG entry rule, do the tests below:

Network Watcher's IP flow verify or Next hop capability can help you understand if a rule is blocking your traffic.

It is possible to have more than one NSG, at the NIC level and at the subnet level

In Network Watcher, access the effective security rules, find out if you have more than one associated NSG:

Bellow the official documentation to troubleshooting RDP Connections:

Answer 2

Thanks for the help. I checked my inbound rules on my NSG (only one) and it appears to be setup correctly. In the Connection section of the VM, I clicked the "Test Network security groups" link, but it does not seem to recognize the rule exists. Still get "access denied" due to DefaultRule_DenyAllInbound.

I also reset the VM configuration, reset the NIC card with a static IP and tried IP Flow Verify, which also said access was denied due to the DenyAllInbound.
