The first thing, and I think it is the cause of the problem, is what I pointed out in the previous mail. It looks like your al0 NIC seems to believe that its MAC address is ff:ff:ff:ff:ff:ff, the broadcast address. And it looks like the Win98 machine is not buying that. Now, the Win98 machine... what kind of card does it have? I can't seem to find a manufacturer who has the 19:02:16 prefix. Something weird is going on. All of this is a problem at the data layer and has nothing to do with your IP settings, NAT, etc. > On Sat, 25 Nov 2000, Crist J .
