If you have console access to the server after it stops accepting 
connections, maybe you should try a tcpdump on the interface and then 
trying to connect with ssh or something, see if any packets come in.

After that maybe try an ssh to localhost from the console. How is the 
network configured, from /etc/network/interfaces, or with NetworkManager 
(if you say you installed ubuntu-desktop on it) ?
