XADM: Service Pack Update Fails on Exchange Standard Edition Running on a Cluster Node
Article ID: 199662

APPLIES TO
- Microsoft Exchange Server 5.5 Standard Edition
This article was previously published under Q199662
SYMPTOMS
If you install Microsoft Exchange Server 5.5 Standard Edition on one of the nodes participating in a Microsoft Cluster Server Configuration, you will not be able to install any Exchange Server 5.5 service pack.
This affects all servers with Microsoft Exchange Server not using the Cluster option but running on one cluster node in the cluster.
CAUSE
This problem occurs if you install Microsoft Exchange Server 5.5 Standard Edition on a computer that you later upgrade to form a cluster by upgrading the operating system to Windows NT 4.0 Enterprise Edition and Microsoft Cluster Server.
The update executable file for Exchange Server 5.5 service packs is cluster-aware, so the update program will see that Exchange Server is not properly installed in the cluster environment and will fail.
WORKAROUND
This is by design.
If you want to run Microsoft Exchange Server 5.5 on a cluster, you must install the Enterprise Edition of Microsoft Exchange Server 5.5.
