<div>
Review data location and NTFS permissions, cluster service needs at least read at the shared folder. 
Review share settings in cluster admin. 

</div>

<div>
NTFS permissions are read on the shared folder, nothing has changed for the share settings in cluster admin since day cluster brought online.
</div>

<div>
Is the cluster service running under a service account? 
Are the NTFS perms just at the shared folder or all the way down from the root? 
 
The error 64 seems to indicatates the share can't find the folder path.

Microsoft is now working on the problem, it is a resource issue and they are trying to determine which resource is causing the problem. Once this is fixed I will post back the solution.

Cluster Server

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
