Hi robasc, just had another thought. When you updated the subnet mask from 255.255.255.128 to 255.255.255.0 in the DHCP server config file, did you also update the /etc/exports for the nfs server, as I've just noticed on your webpage it was still using 255.255.255.128, which might explain why the NFS isn't mounting.
Hello BigJimJams, Yes I did, in fact I freshly installed the whole thing again using the subnet you gave in the tutorial.

But still having the same problem.

There are a couple of things I am wondering here and you might have already noticed on the webpage is that I am using intrepid amd64 version.

I had to modify the updates for intrepid rather than hardy. Also I had to modify:

debootstrap --arch i386 hardy /nfsroot/kerrighed http://archive.ubuntu.com/ubuntu/
To:

debootstrap --arch amd64 intrepid /nfsroot/kerrighed http://archive.ubuntu.com/ubuntu/
I am not sure if this has anything to do with it.

Another problem I experienced is when I had to add a user in /nfsroot/kerrighed.

When I checked the /etc/sudoers file there was no user installed so I had to manually install the user as noted in the webpage.

This was just a couple of things I have been wondering about.

I really do not know what else to do but I am trying to think of something.
