Error 101 is ENOTUNREACH, which implies you don't have the proper 
netmask or gateway setup; so it's probably a DHCP configuration problem.

Note to everyone: I recommend using the kernel's own DHCP service, and 
*NOT* using IPAPPEND in most cases.  The IPAPPEND option is supported 
because of some DHCP configurations where that would obtain two 
different IP addresses.
