Not Authoritative for Subnet 192.168.1.0

Hi Bruce,

What got me off here is that the ipconfig/all replied the correct ip  
address and no NIC problems at all. I solved it in looking my router  
which wasnt doing well with DHCP. So Vista is as well working now. My  
second pb is that I have two NIC on my Vista box, and DHCP constently  
connects to the second one which throws off SQUID. Is it possible to  
force DHCP to connect to one NIC instead of the other? I thought that  
by adding a static IP address that would do the trick but obviously  
it doesn't.

Cheers

Stephane
