How to Automatically Obtain an IP Address

Follow these steps to configure the computer to obtain an IP address from a DHCP server. Note that you must have a DHCP server.
  1. Click Obtain an IP address automatically.
  2. Click Obtain DNS server address automatically if you do not want to specify the IP address of the Domain Name System (DNS) server.
  3. Click OK. In the Local Area Connection Properties dialog box, click Close.
  4. In the Local Area Connection Status dialog box, click Close.
  5. Click Start, and then click Run.
  6. In the Open box, type cmd, and then click OK.
  7. At the command prompt, type ipconfig /release, and then press ENTER.
  8. Type ipconfig /renew, and then press ENTER.

    The network adapter is assigned an IP address by the DHCP server, and a message similar to the following appears:
    Windows Server IP Configuration

    Ethernet adapter Local Area Connection:

    Connection-specific DNS Suffix . :dns.microsoft.com
    IP Address. . . . . . . . . . . . :192.168.0.201
    Subnet Mask . . . . . . . . . . . :255.255.255.0

Troubleshooting

  • There is an IP address conflict: If you try to assign an IP address that is already in use, you receive the following error message:
    The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.
    In this case, assign an unused IP address to the network adapter.
  • Your computer cannot connect to other computers on the network: If you assign an incorrect subnet mask address to the network adapter, the computer is effectively located on a different network. You cannot connect to other computers on the network.
  • Your computer cannot connect to other computers by using host names: If you assign an incorrect DNS server IP address, or if you do not use a DNS server, you cannot connect to computers by using their host names. This prevents you from browsing the Internet. You can connect to other computers by using their IP addresses.

    To work around this issue in a local network, add host-name-to-IP-address mappings in a Hosts file.
