(type BuildServiceHostOwnershipException) Exception Stack Trace: at Microsoft.TeamFoundation.Build.Hosting.BuildMachine.StartOperation.End(IAsyncResult result, HttpRouter& router, TfsMessageQueue& messageQueue, List`1& processHosts, MachineLifecycleActivity& traceActivity) at Microsoft.TeamFoundation.Build.Hosting.BuildMachine.EndStart(IAsyncResult result) at Microsoft.TeamFoundation.Build.Machine.WindowsService.EndStartMachine(IAsyncResult result)
