Ok sometime ago I changed my ip address to a static one because I was bored and I wanted to learn more about static ips. I am running windows xp. My laptop works find on the network that i set up a static ip address, but when i go to another network, the incorrect dns servers are being used. When I enter the option to get a dns server automatically, the internet connection works but only for a short time. After that the dns servers resets to the one i entered manually on a previous network.

I did this by going to Network Connection->Right Click Local Area Connection and go to properties->Select TCP/IP -> then click the Properties button.

At this point i am given the option to Obtain an ip address or obtain and address automatically. My question is how do I resolve this problem of the dns server reseting to the previous one.
