TFS build service cannot connect to a TFS 2012 server - seeing EventID 206 MessageQueue in error log
Whilst setting up our new TFS 2012 instance I had a problem getting the build box to connect to the TFS server. When I started the build service (on a dedicated VM configured as a controller and single agent, connected to a TPC on the server on another VM). All appears OK, the controller and agents said they were running and state icons went green About 5 seconds later the state icons go red, but message says the controller and agents are still running, from past experience I know this means it is all dead....
