*****************************************
I understand about the "link local block".
It would seem obvious that the client is not seeing
the dhcp server, in this case the router.
Since I started this thread, I suspected a winsock
problem so I ran a small routine called Winsockfix.exe.
It re-establish the links and all is well.
Thanks for all input!
