Help! SP2 RC2 (build 2149) installation failure

> Hi all,
>
> I got SP2 RC2 installation failure. An extended error has occurred while

> seems work fine, stating SP2 build 2149 installed, except I found the Network
> Connections panel has gone.
> It's now nothing happen when I click the Properties of My Network Places
> from the desktop nor the Network Connections from Control Panel. In fact,
> those network connections defined before RC2 are there and work fine.
>
> How may I mend this broken link to invoke the Network Connections page?
> Any advice would be highly appreciated.
