• Make sure you have “Obtain Automatically” selected.

• You can verify your settings by running ipconfig /all at a Command Prompt

Note: On Windows 2000 and NT you need to run Regedt32 instead.

• Navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
\Interfaces\{B003AD4A-B6DB-44FD-9741-CBA3C51B6498}

(actual GUID of the NIC may vary, select the one that represents your own NIC)

• Select the IPAddress key and double click it.

• In the Edit Multi String dialog box enter a second (and third and so on) IP address. Make sure you enter each IP on a separate line. Click Ok.
