NFS error report

[Paulo Henrique Baptista de Oliveira]

        Hi Debian users,
        I mounted the directories /usr/local and /home in a PC 486 client from 
a Pentium (server). The mount was sucefully but at boot the çlient gives me the 
error: 
        NFS: notice message: result = -101.
        several times.
        What is wrong?
        Have a nice day,                        Paulo Henrique
