A variety of services and applications can work as "cluster-aware" applications, functioning in a coordinated way with cluster components.

	Note
	When configuring a service or application that is not cluster-aware, you can use generic options in the High Availability Wizard: Generic Service, Generic Application, or Generic Script. For information about using these options, see Understanding Generic Services and Applications that Can Be Configured in a Failover Cluster.

In the High Availability Wizard, you can choose from the generic options described in the previous note, or you can choose from the following services and applications:

• DFS Namespace Server: Provides a virtual view of shared folders in an organization. When a user views the namespace, the folders appear to reside on a single hard disk. Users can navigate the namespace without needing to know the server names or shared folders that are hosting the data.
  
  
• DHCP Server: Automatically provides client computers and other TCP/IP-based network devices with valid IP addresses.
  
  
• Distributed Transaction Coordinator (DTC): Supports distributed applications that perform transactions. A transaction is a set of related tasks, such as updates to databases, that either succeed or fail as a unit.
  
  
• File Server: Provides a central location on your network where you can store and share files with users.
  
  
• Internet Storage Name Service (iSNS) Server: Provides a directory of iSCSI targets.
  
  
• Message Queuing: Enables distributed applications that are running at different times to communicate across heterogeneous networks and with computers that may be offline.
  
  
• Other Server: Provides a client access point and storage only. Add an application after completing the wizard.
  
  
• Print Server: Manages a queue of print jobs for a shared printer.
  
  
• Remote Desktop Connection Broker (formerly TS Session Broker): Supports session load balancing and session reconnection in a load-balanced remote desktop server farm. RD Connection Broker is also used to provide users access to RemoteApp programs and virtual desktops through RemoteApp and Desktop Connection.
  
  
• Virtual Machine: Runs on a physical computer as a virtualized computer system. Multiple virtual machines can run on one computer.
  
  
• WINS Server: Enables users to access resources by a NetBIOS name instead of requiring them to use IP addresses that are difficult to recognize and remember.
