When I try to do NFSStart, or load pkernel on its on, it unload with
the message:
PKERNEL: Cannot Initialize Portmapper

load pkernel -usexnfstcppmap does not work either:

Loading module PKERNEL.NLM NetWare NFS - Portmapper and RPC Module
Version 15.01.26 May 31, 2005 Copyright (C) 1995-2005, Novell,

disabled. When XNFS.nlm is loaded, the TCP Portmapper services will
be provided by it. PKERNEL: Cannot Initialize Portmapper NetWare
Product Kernel is unloaded.

Kind regards,
