Error 93 is EPROTONOSUPPORT.  Is there a firewall between client and 
server?  tcpwrappers on either end?  Are you using a motherboard NIC 
that silently hijacks a reserved UDP port?

Try capturing a network trace with "tcpdump -s0 -w /tmp/dump" on your 
server while your client boots.  Take a look at it with wireshark or 
tethereal.
