Limitations of Server Clusters
This topic covers important limitations of Windows 2000 server clusters.
You can use Terminal Services for remote administration on a server cluster node. You cannot use Terminal Services for application server on a server cluster node.
NOTE: Because clustering is not supported in Microsoft Terminal Services, it is, therefore, not supported in Citrix MetaFrame.
Please see Microsoft TechNet Article Q294926 for additional information about this topic
The Clustering concerns discussed in these references do not apply, when considering fault tolerant configurations, for the MetaFrame XP DataStore. Please refer to the MetaFrame XP/FR1 Advanced Concepts Guide for information about MetaFrame XP DataStore and fault tolerant configurations.
