SYMPTOMS
When you run the IIS_switch.bat file during the upgrade of a Microsoft Cluster Service (MSCS) cluster that contains Internet Information Services (IIS) from Microsoft Windows 2000 to Windows Server 2003, you may receive the following error message:

Group &quot;Cluster Group&quot; will be ignored. Group contains an IIS server instance, which is not supported.



CAUSE
This problem occurs because the IIS resource is defined in the default cluster group.



MORE INFORMATION
Microsoft does not recommend that you put other resources in the default cluster group. This configuration might affect the availability of the whole cluster. If IIS fails, it causes the group to fail.

The default cluster group typically contains the quorum disk. During failover of the quorum disk, the whole cluster is in a transition state and other failovers cannot occur because they are queued waiting for quorum disk to come back online.

Having other applications writing to the quorum disk can potentially fill the quorum disk and will make the cluster unavailable.



RESOLUTION
To resolve the error and continue the upgrade, follow these steps:  Delete the IIS resource from the default cluster group.

For more information about how to delete the resource, see the documentation (also included with Windows Server 2003) at the following Microsoft Web site:
