Cannot use 32-bit resources on a 64-bit server clusterArticle ID: 312090 - View products that this article applies to. This article was previously published under Q312090 SYMPTOMS When you try to install or bring online a 32-bit resource
on a 64-bit server cluster, you may experience unexpected results.
Specifically, the resource may not come online, or it may constantly attempt to
failover to another node. CAUSE This behavior occurs because 64-bit processes cannot
directly load 32-bit DLLs. Therefore the Resource Monitor (64-bit process)
cannot directly load a 32-bit Cluster Resource DLL. Typically Cluster Resource
DLLs are directly loaded in the process space of the Resource Monitor, and this
means that only 64-bit DLLs can be loaded under the 64-bit Resource Monitor
process. RESOLUTION Contact the vendor that created the program or cluster
resource to obtain an updated 64-bit version. Microsoft Exchange 5.5, Microsoft
Exchange 2000, Microsoft SQL 7.0 and Microsoft SQL 2000 use 32-bit cluster
resources and are not supported on 64-bit server clusters. MORE INFORMATION To help determine if a cluster resource is 32-bit or
64-bit, use the VFI utility that is included in the Windows Server 2003
Resource Kit. For more information, click the following article number to view the article in the Microsoft Knowledge Base: 875423

Support for 32-bit programs on 64-bit server clusters is included in Windows Server 2003 Service Pack 1 and in x64-based versions of Windows Server 2003
