JSI Tip 10322. Your receive 'Invalid Class String' when SQL Server connects to a Cluster Server through the Cluster Administrator?

When SQL Server connects to a Cluster Server through the Cluster Administrator, you receive:

An error occurred attempting to read properties for the "Microsoft Search Service Instance" resource type.
Invalid Class String
Error Id -2147221005(800401f3)

                 OR
An error occurred attempting to read properties for the 'Microsoft Search Service Instance' 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.

NOTE: The resource type may be different in your environment.

This error results from a missing DLL in the %systemroot%\Winnt\Cluster folder, like Gathercl.dll, or from not having sufficient permissions to access the folder.

To workaround this problem:

1. If %systemroot%\Winnt\Cluster\Gathercl.dll is not present, copy it from the Service Pack file, or the SQL server CD-ROM.

2. Register the Gathercl.dll file, using Regsvr32 /S Gathercl.dll.

3. Make sure that the logged on account has Full Control permission on the %systemroot%\Winnt\Cluster folder.
