Hi Corey

Looking at the network traces you sent me:

Good machine: We see a DNS request and response that resolves the name to
an IP address:

Request - DNS: 0x2623:Std Qry for www.yahoo.com. of type Host Addr on class
INET addr.
Response - DNS: 0x2623:Std Qry Resp. Auth. NS is www.yahoo.com. of type
Canonical name on class INET addr.

If you expand these in Network Monitor, you can see them in much greater
detail.

Bad machine:

Request - NBT: NS: Query req. for WWW.YAHOO.COM <00>

There is no response.

The request on the bad machine isn't a DNS request but a NETBIOS request.
This suggests to me that the bad client isn't correctly configured to use a
DNS server or possibly the DNS Client service is not started. I can see
from the good trace that the DNS server being used for successful name
resolution is 152.1.1.206.

Kind regards
