Hi there,

Just as a reminder:

The applied simple patch allows one to detect and handle the case where no lease 
could be obtained via DHCP. (Just add a section "failed" to your script.)

This might come handy when one wants to implement some kind of APIPA behaviour as 
use by M$ and as described earlier.

Thanks,

Steven
