Server Clustering - Please read Microsoft Knowledge Base article: 935197



CAUSE
This behavior occurs because this Windows Server 2003-based server is in a cluster. Windows Server &quot;Longhorn&quot; does not support an upgrade of clustered servers from Windows Server 2003 to Windows Server &quot;Longhorn.&quot;



WORKAROUND
To work around this behavior, use one of the following methods, as appropriate for your situation.

Method 1: Clean install

 * 1) Perform a clean installation of Windows Server &quot;Longhorn&quot; on the nodes in the cluster.
 * 2) Install the Failover Clustering feature, create a new cluster, and then reconfigure the cluster settings.

Method 2: In-place migration

 * 1) Use the Cluster Administrator tool (Cluadmin.exe) to evict the Windows Server 2003-based server from the cluster.
 * 2) Upgrade the operating system to Windows Server &quot;Longhorn.&quot;
 * 3) Install the Failover Clustering feature, and then create a new cluster with this node.
 * 4) Use the Migrate a Cluster Wizard to migrate certain settings from a clustered server that is running Windows Server 2003 to a clustered server that is running Windows Server &quot;Longhorn.&quot;
 * 5) As soon as you have completed migrating the settings, evict the remaining nodes, perform an upgrade Windows Server &quot;Longhorn,&quot; and then join the nodes to the new Windows Server &quot;Longhorn&quot; cluster.



STATUS
This behavior is by design.



MORE INFORMATION
