Backup Exec 12.5 Remote Agent turn off automatically

Hi,

I encounter some problem with my Symantec backup exec 12.5. I notice that my remote agent services was been turn off might be due to when the server been rebooted that the reason that the backup was unsuccessful. Today again such thing happen but the server wasn't rebooted. The services was set to automatic it should have started by itself but it didn't. What is the cause of this problem what is there any solution to it. Need your advice and guidance in this. Please refer to my attachment for better illustration.
