Having looked at the DNS setup window I must admit that I don't know what to put in the Host and Domain fields. I am not running a DNS server so DNS lookups are done through my ISP.
On my (working) Win98 config I do not have DNS enabled for the TCP/IP->NIC binding. I recall that this terminology appears slightly differently in the Win95 version of the networking control panel but AFAIR it is in there somewhere.
