How to Setup Visual Studio (TFS) Test Agents in the Cloud

We ran into some issues trying to get the Visual Studio Test Agents to register and communicate with the Visual Studio Test Controller when the controller is inside our network, and the agents are in the cloud. There are some strange quirks that need to be addressed before this will work.

The IP Address You Have Entered for this Network Adapter is Already Assigned to Another Adapter

If you have ever replace and NIC card, either virtual or physical, and used the same static IP address as the old card had, you probably recognise the error below.

The IP address XXX.XXX.XXX.XXX you have entered for this network adapter is already assigned to another adapter <Name of adapter>. <Name of adapter> is hidden from the network and Dial-up Connections folder because it is not physically in the computer or is a legacy adapter that is not working. If the same address is assigned to both adapters and they become active, only one of them will use this address. This may result in incorrect system configuration.

Do you want to enter a different IP address for this adapter in the list of IP addresses in the advanced dialog box?
