This behavior occurs because this Windows Server 2003-based
server is in a cluster. Windows
Server 2008
does not support an upgrade of
clustered servers from Windows Server 2003
to Windows Server 2008.

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 2008 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
2008. |
| 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 2008. |
| 5. | As soon as you have completed migrating the settings, evict
the remaining nodes, perform an upgrade
Windows Server 2008 and then join the
nodes to
the new Windows Server 2008 cluster. |

This
behavior is by design.
