When I check DFAgentLogs,I found:

2011-11-9T6:15:8.855, 74532, 7, Error, 0, 39704eea-7c1c-41d9-876b-c32fe169b17b`GetAgentState`System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://localhost/dfagent/1/host. The connection attempt lasted for a time span of 00:00:02.0081149. TCP error code 10061:No connection could be made because the target machine actively refused it 127.0.0.1:808.  ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:808
   at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress)
   at System.Net.Sockets.Socket.Connect(EndPoint remoteEP)
   at System.ServiceModel.Channels.SocketConnectionInitiator.Connect(Uri uri, TimeSpan timeout)
   --- End of inner exception stack trace ---

So,I checked the port 808 and terminate the existing process
