Responsiveness of User-Mode Processes on Node

Updated: November 25, 2009

Applies To: Windows Server 2008 R2

The Cluster service monitors the node to ensure that it does not remain in a state where essential processes are running (the kernel is running) but the node is unresponsive (user-mode processes cannot run). Unless the node is functioning both at the kernel level and the user-mode level, it cannot respond to client requests.
