The LoadOrderGroupDependencies parameter passes a list of load ordering groups that must start before this service. The array is doubly null-terminated. If the pointer is NULL or if it points to an empty string, the service has no dependencies.  Group names must be prefixed by the SC_GROUP_IDENTIFIER (defined in the WINSVC.H file) character to differentiate it from a service name, because services and service groups share the same name space.  Dependency on a group means that this service can run if at least one member of the group is running after an attempt to start all members of the group.
