Lab Solution

From the Instances blade in the Portal you can choose an instance to open, and from the VM instance page you have the Connect option:

• choose RDP
• ignore any errors you see listed - the connection will work fine with the current setup
• select the Load balancer public IP address
• download the RDP file, open it in your client and connect with admin credentials

When you’re connected, open PowerShell and run:

# print all the Windows Services:
Get-Service

# then stop the IIS WWW Publishing Service:
Stop-Service w3svc

You can confirm the web server is no longer running on that instance:

# this will show a connection refused error:
curl.exe localhost

On your host machine, browse to the PIP address with repeated GET requests:

curl http://<pip>

You’ll only see responses from the instance which you didn’t choose for stopping the web server.

In the Portal you can’t see that health probes are failing. This is a basic SKU load balancer, and that detail only gets provided for more advanced SKUs.
