Backup Exec 2014_TCP error code 10061: no connection could be made because the target machine actively refused

Hi everyone

I need some help. I have installed Symantec Backup Exec 2014 on a Windows Server 2012 R2 Std. I have use the local administrator account for the installation and the login. The installation have been quite easy. However, when I start Backup Exec 2014 it always give me an error msg: "Could not connect to net.tcp//[server_name]:50104/BEMService/ServerData. The connection attempt lasted for a time span of 00:00:02.0002511. TCP error code 10061: No connection could be made because the target machine actively refused it [server_ip]:50104."

I have found that some users have posted this problem on the forum. I have try to have a look about the solution proposed in the forum. Like creating a new rule in the Firewall setting, I have also disable the firewall. The problem is still there. I have noticed that some services is not started. Unfortunately, I cannot start them. They always give error message like: "Error 1068: The dependancy service or group failed to start". The services are:

1. Backup Exec Remote Agent for Windows
2. Backup Exec Agent for Browser
3. Backup Exec Device & Media Service
4. Backup Exec Job Engine
5. Backup Exec Management Service
6. Backup Exec Server

I have try to  change the services execute path using administrative command in windows environment, the problem is still the same. Can someone help me please... 

Thanks.
