Configuring Windows 7 to use DHCP

  • On your keyboard, press the Windows key () and the letter "r" together-- to open the Run Dialogue box.
  • Type ncpa.cpl in the dialogue box and press Enter.

  • Right-click on the desired network adapter and select Properties.

  • Double-click Internet Protocol Version 4 (TCP/IPv4) to open the Properties window.
  • Select or verify Obtain an IP Address Automatically is selected.

    Note: If the radio button "Obtain an IP address automatically" is active, as in the image above, your computer is configured to use DHCP.

  • Click on the Advanced button.
  • Click on the DNS tab. Make certain the following DNS suffixes have been entered into the field marked Append these DNS suffixes (in order).

  • If these suffixes are not entered, click on the Add button and add each of the following entries:
    • alias.cs.cmu.edu
    • scs.ad.cs.cmu.edu
  • Click on OK until the network dialogue boxes are closed.
  • Reboot your system.
This specific adapter is now set for DHCP. Note that this change will only need to be made to your hard-wired Ethernet adapter. Other adapters listed in this section (1394 firewire adapters, loopback adapters, etc.) may be ignored. If you have problems determining which adapter is appropriate, contact the SCS Help Desk at help@cs.cmu.edu or x8-4231.
