Novell is typically running computer system on IBM PC-compatible hardware, providing file and print sharing services to personal computers. Novell Netware server crashes due to corrupt volumes after damage in file data structures, an accidental disk format, virus attack, human error, partition loss, software malfunction, file or directory deletion, corrupt or damaged partition table, drive not booting and so on.

This happens when NDS (Novell Directory Services) in Novell OS get damaged.

Directory services are databases of information for storing, accessing, managing, and using different kinds of information about users and resources in a computing environment. Novell Directory Services (NDS) is an object-oriented implementation of directory services based on X.500 that allows one to build sophisticated naming schemes and databases across network-wide resources. The NDS architecture provides global access to all the network resources regardless of their physical location, forming a single information system.
