Enable Random Adapter Responses

For a computer with multiple network adapters, this setting specifies whether to respond with an IP address selected randomly from the range of addresses on the computer or whether to return the IP address of the adapter that the request came in upon.

Open your registry and find the key below.

Create a new DWORD value (or string value for Windows 98) named "RandomAdapter" and set it to "1" to enable random adapter addresses or "0" to disable them (the default).

Restart Windows for the change to take effect.


Settings:
System Key: [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP]
Name: RandomAdapter
Type: REG_DWORD (DWORD Value)
Value: (0 = disabled, 1 = enabled)
