Note: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Use Registry Editor at your own risk. You should back up the registry before you edit it. If you are running Windows NT or Windows 2000, you should also update your Emergency Repair Disk (ERD).
Disable the Media Sense feature:
1.Start Registry Editor (Regedt32.exe).
2.Locate the following key in the registry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
3.On the Edit menu, click Add Value, and then add the following registry value:
Value Name: DisableDHCPMediaSense
Data Type: REG_DWORD
Value: 1
4.Quit Registry Editor, and then restart the computer.
The network adapter still shows the "disconnected" status, but the cluster installation process can detect the adapter as available for cluster communication.
Alternatively, when you install the Cluster Service on the first node, you can have the second node powered up to the Control M (<Ctrl> <M>) menu. On the first node, a network connection will be detected for the private network.
