NFS on Redhat 9

I have been trying to network two computers both with Redhat 9 on them, they are connected through a hub with ip addresses 192.168.1.101 and 192.168.1.102. I have been following the directions on http://www.troubleshooters.com/linux/nfs.htm, except I have not put anything in host.deny. When I try to run the command "mount -t nfs -o rw 192.168.1.101:/home /mnt/share" I get "mount: RPC: remote system error - Connection refused" and if I change the ip to end in 255, "Connection refused" becomes "Network unreachable". Does anyone know what's wrong or a good step by step tutorial?

Thanks
