Error Message:

The DllName value for the name !ws! resource type does not exist. Resources of this type will not be monitored. The error was number !d!.

Explanation:

This error occurs when you're defining a new resource in order to install a new component (which the resource manages). Certain parameters are required when defining a resource type, and the Cluster service couldn't find one or more of the required parameters. Either the resource type has been defined without a required parameter, or setup of the component failed to supply the required parameter. Failure to define the resource type could occur if, for example, the component setup was interrupted.

User Action:

Reinstall the component for which the unknown resource type is being specified, then redefine the resource. If you are manually defining the resource type, specify the missing parameters.
