Changing DNS Settings - Windows Vista

Left-click the Windows logo at the lower left corner of the screen.

Left-click "Control Panel." (This opens up a new window.)

Double-click "Network and Sharing Center." (This opens up a new window.)

At the upper-left portion of the Network and Sharing Center window, find and left-click "Manage Network Connections."

The system will prompt you to verify that you had initiated that request. Click "Yes."

Right-click "Local Area Connection." (This opens up a small drop menu.)

Left-click "Properties." (This opens up a new window.)

Within the center of the Local Area Connection window, you will see a small scroll box with checkboxes on its left and a scroll bar on its right.
Scroll down to "Internet Protocol TCP/IPv4" and left-click that line to highlight it.

With "Internet Protocol TCP/IPv4" highlighted, left-click "Properties" immediately below the scroll box. (This opens up a new window.)

Do not modify any settings in the top half of the Properties window regarding IP addressing.
Instead, click the button in the lower half of this window next to "Use the following DNS server addresses."

Within the boxes below this button, enter the following:
Primary DNS: 206.168.44.12
Alternate DNS: 156.154.70.7

Click "OK" to close the Properties window, then "OK" again to close the Local Area Connection window.
