Error start Nfs

hi
 i have RedHat linux 7.1 , Kernel 2.4.2-2smp , I was using NFS on it and it was working fine , recently I restarted the server and removed teh tape trive from it . after that i am getting the following error when i start NFS :
Starting NFS services:    OK  ]

FAILED]
Starting NFS mountd: Cannot register service: RPC: Unable to send; errno = Invalid argument
FAILED]
Starting NFS daemon: nfssvc: Network is unreachable

on RH7.3 it's in this file:

/etc/sysconfig/network-scripts/ifcfg-lo  
DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback
