nfs error on one computer

Hello,
I have a real real strange problem : I use deploy studio for 16 identical computers (imac 20" bought in december). Everything is fine on 15 computers. On the last one, I find the boot server, the tftpboot image is downloaded fine, than the nfs load begins.. and than.. I have ? unexpected rpc answers ?. I have done an hardware test on the computer and everything seems fine.

Here is the tcpdump transcript of the begining of the failure . (pomme is the server, grenade the booting client).

Re: nfs error on one computer

Did you check the ethernet cables?
Does it happen always on the same computer?
Does it happen on the 16th machine whatever is the computer?
