Source:  LOGIN.EXE

Possible Cause:  The user tried to log in to a server without loading the NetWare NETX or VLM bindery shell into the workstation's memory. When the workstation is booted, DOS is loaded into the workstation's memory. The NetWare shell is then loaded on top of DOS. The shell allows the workstation to communicate with the server. A user cannot log in to any server on the network unless the NetWare shell has been loaded into the workstation's memory.

Action:  Give the user a boot diskette that contains both DOS and the NetWare shell files. Then ask the user to try rebooting the workstation and logging in again. If the error persists, the boot diskette may be corrupted.
