To start or stop a Windows Service, you must be a member of the Administrators group on the local computer, or you must have been delegated the appropriate authority. If the computer is joined to a domain, members of the Domain Admins group might be able to perform this procedure.
You can use the Windows Services control panel, the net command or the sc command to start and stop windows services.
To start and stop a Windows Service using the net command open Command Prompt and use following commands:
•To start a service, type: net start "<service name>"
•To stop a service, type: net stop "<service name>"
The Application Server services are named rbAppSrv_<instance Identifier> , where <instance Identifier> is the instance identification string you chose on installation of the Application Server or an additional Application Server instance.
