deploy resource dll failed

Hi,

I created a cluster resource DLL and manually deployed it by copying the dll
file to all node's c:\Windows\cluster directory and running "cluster
resourcetype /create myresource /dllname:mydll.dll".

When I start the Cluster Administrator program, it shows a popup error
message:

"An error occurred attempting to read properties for the 'myresource'
resource type.

The specified node does not support a resource of this type. This may be due
to version inconsistencies or due to the absence of the resource DLL on this
node.

Error ID: 5079[000013d7].

Do you want to ignore this error and continue?"

Even I tried the SDK sample ClipBook Server, it shows the same error.

What's wrong with the resource DLL or the cluster environment?

Thanks for your help,

Shangwu
