In-Depth Information
NCP is a series of server routines designed to satisfy application requests coming from, for example, the
NetWare shell. Services provided by NCP include file access, printer access, name management,
accounting, security, and file synchronization.
NetWare also supports the Network Basic Input/Output System (NetBIOS) session layer interface
specification from IBM and Microsoft. NetWare's NetBIOS emulation software allows programs written
to the industry-standard NetBIOS interface to run within the NetWare system.
NetWare application layer services include NetWare Message Handling Service (NetWare MHS),
Btrieve, NetWare-loadable modules (NLMs), and various IBM connectivity features. NetWare MHS is
a message delivery system that provides electronic mail transport. Btrieve is Novell's implementation of
the binary tree (btree) database access mechanism. NLMs are implemented as add-on modules that
attach into the NetWare system. NLMs for alternate protocol stacks, communication services, database
services, and many other services are currently available from Novell and third parties.
Troubleshooting Novell IPX
This section presents protocol-related troubleshooting information for Novell IPX connectivity and
performance problems. It describes specific Novell IPX symptoms, the problems that are likely to cause
each symptom, and the solutions to those problems.
The following sections outline the most common issues in Novell IPX networks:
•
Novell IPX: Client Cannot Connect to Server on Same LAN
•
Novell IPX: Client Cannot Connect to Server on Remote LAN
•
Novell IPX: Clients Cannot Connect to Server over Public Switched Network (PSN)
•
Novell IPX: Client Cannot Connect to Server over Integrated Services Digital Network (ISDN)
•
Novell NetBIOS: Applications Cannot Connect to Server over Router
•
IPX RIP: No Connectivity over IPX Routing Information Protocol (RIP) Router
•
