Windows 7 name resolution looking at wrong domain
Click on Start, Control Panel, Network and Sharing Center, Local Area Connection, and in the window that pops up, click on properties. Then click on Internet Protocol Version 4 (IPv4). Click on the Properties button, then click on Advanced. In the window that opens, click on the DNS Tab. If the DNS suffix box is filled, clear it.

My home Windows 7 PC is having problems with a DNS lookup. I have several machines in my home network including one called "ROSE". When I execute
ping ROSE
from a command prompt, the ping is against the external IP address for the server "ROSE.mycompany.com" (a server at the company where I work). If I doping TULIP
(another machine in my local network) the ping is executed (correctly) against the machine in my home network; note that there is no TULIP registered in the "mycompany.com" domain.My guess is that the name resolution looks in the "mycompany.com" domain first; if no result it then looks locally.
I cannot figure out why the name resolution is looking at "mycompany.com". I do have a company Cisco VPN client installed, but not currently installed. Here is the output from
ipconfig

What else should I be looking for?

rlandster over 11 yearsThe computers full name is "DAISY.mycompany.com". Ah. That fixed it. The setting was under that System properties "Primary DNS suffix of this computer".
