Recently I upgraded symantec backup exec 10.1 5629 to the latest version (SP4). Since then I was unable to start the backup exec service, I was getting the error
"faulting application bengine.exe, version 10.1.5629.44, faulting module nt.dll"
I tried a few things to fix this including:
Start -> run -> 'DCOMCNFG', expand component services, computers. Right click 'My computer' -> properties, Com Security and adding the admin account back but this didn't work.
While trying to start the service, I noticed and option "Service credentials". I put in all the existing details (same admin account, same password, same domain) and clicked save.
After doing this and entering all details in any Symantec popups, the services all started.
