NetWare Core Protocol (NCP)
NetWare Core Protocol. Procedures that a server’s NetWare operating
system follows to accept and respond to workstation requests.
The process of requesting service from a NetWare server begins in the
workstation’s RAM where the NetWare DOS Requester or NetWare .
The Requester then hands the requests to the station’s IPX communication
protocol. IPX transmits the request to the server after attaching a header
designating the source and destination.
Upon receiving the request, the server removes the IPX header and reads the
request.
Because the NetWare Requester formed the request using the exact
guidelines of a specific service protocol, the server handles the request
according to the protocol rules, resulting in a proper response.
NetWare Core Protocols exist for every service a station might request from
a server.
Common requests handled by NCP include creating or destroying a service
connection, manipulating directories and files, opening semaphores, altering
the Directory, and printing.

NetWare Diagnostic Daemon (NWDIAGD)
Provides IPX/SPX diagnostic services across an internetwork.
NWDIAG receives and answers diagnostics requests about a network in
accordance with the network’s configuration. The diagnostic services enable
applications to
• Identify internetwork nodes
• Build an internetwork map
• Query one or more nodes on an internetwork
• Identify software components on different nodes
• Provide information about those components
• Perform point-to-point packet transmission efficiency tests
