TFS 2012: Create New Build Service for another Collection

Multiple collections exist in our TFS server 2012 eco system. If you open TFS Administration console, it gives you option to configure build service and corresponding controller/ agent for one Collection.

How do I activate Build controller for other collections? link is of really very useful post by Jim lamb. Thanks Jim.

Here is the steps:

1. Create a new build service on your Build Server.

2. Set env variable

3. Start the TFSMgmt ( Admin console) on command prompt. Admin console Interface will not recognize the env variable.

4. Configure Controller/ Agent as usual. Puhh.. Done..
