Hi Tom.

The "Hostnames" tab shows:

machine's hostname = localhost

Nameserver addresses = 192.168.0.1

There is nothing else, and that is the address of my DLink router.

LAN domain searchlist = NO Entries

All the other boxes are blank.

I am not sure I answered all of your questions. If not, please let me
know.

Thanks,
Sandy
