When you’re preparing your virtual machine for use in a lab managed environment, there are a number  of steps that need to be done to each virtual machine.

To enable testing, build-deploy-test workflow and network isolation capabilities on the Lab Environments, you need to install Visual Studio Test Agent, Visual Studio Lab Agent and Team Foundation Build Agent on VMs and templates that are part of the Lab Environments.

The good news is there’s a great tool that has just been updated to work with the RC release. This VM Prep Tool takes care of installing and configuring these agents using scripts that you can just sit back and watch while the work is being done.

The tool can update existing Beta 2 agents to the RC versions and now offers two modes of operation: Self Service Mode and Admin mode.
