DOCUMENT:Q199662 02-MAY-1999 [exchange] TITLE :XADM: Service Pack Update Fails on Exchange Standard Edition PRODUCT :Microsoft Exchange PROD/VER:winnt:5.5 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- 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.
