x64 MS DTC failed

I've successfully setup 2 nodes cluster on Windows2003 Server Enterprise R2
SP2, tested everything ok, now before I setup SQL2005 cluster, I'm following
KB301600 to configure MS DTC but I have great difficulty to do it.

In 'Notes' section, it says:

You should not put the MS DTC resource online before you follow the
instructions in the Microsoft Knowledge Base (KB) 817064 article to enable
Network DTC Access.

For Windows Server 2003-based computers that are running Service Pack 1 or a
later service pack, do not follow the steps in the KB817064 article yet.
First, you must complete the steps in the following "More information"
section to add the MS DTC resource to the cluster. Then, you can follow the
steps in the KB817064 article to complete the configuration.

Here is my problem: After I created 'MS DTC resource' and follow KB817064 to
enable network DTC, as soon as I enabled network DTC in add/remove programs
the DTC resource in cluster adminsitrator attempts to go online and
repeatedly fails.

Did I miss anything? What is the correct order to do this? Please help!
