Also i have started the nfs server on 11.0.0.3.
So what is the next step to be followed.

use mount command to do it or make a manual entry in fstab for permanent mounting every time system starts.
"man mount"
Which version of Linux u r using?

make sure you have an etry as the following in /etc/exports file:
/home/exper/shared 11.0.0.5/32(rw)

rw here means read+write - use ro for read only.
then restart the nfs service:
service nfs restart
then make sure the firewall (iptables) allows the traffic.

from 11.0.0.5 issue the command:
showmount -e
the output should list the available shares -f you get it, then basically you should be able to mount the directory.

Very important thing is to assign points.

In the exports file on server i have included the directory as /home/exper/shared *(rw,no_root_squash)
and i have restarted the nfs and nfslock service now and still i get the following error message mount to NFS server '11.0.0.0.3' failed: server is down

I have even restarted the nfs and nfslock on the client machine not sure what to do about this.

1. check the ip address.
2. From server, run `showmount -e` to see the available shares. If shows nothing - the share isn't there.
3. From client run `showmount -e 10.0.0.3`.

First check connectivity between these 2 servers (ping) and make sure the ports aren't blocked with firewall.

try with the full path:
/usr/sbin/showmount -e

if not found - install the nfs-utils rpm.

by default Red Hat turns on the firewall during install, try running /etc/init.d/iptabls stop and then see if the client can get access. If it works, then you need to either leave the firewall off or set it up to pass the proper ports for NFS
