Well, I asked for the output of 'showmount $server' and what /etc/exports shows (not just the options) because I suspected you are having a name resolution problem at startup. Your responses so far appear to confirm this possibility. How is the network configured on this server - via NetworkManager, or via ifupdown (/etc/network/interfaces)? How does this server do DNS resolution: does it have a local DNS server, or is it pointed at another server somewhere on the network?
