SYMPTOMS
When you try to use the Cluster Administrator console on a Microsoft Windows Server 2003-based computer, the console may not finish its startup. Additionally, you may experience the following symptoms:
 * The console stops responding when it enumerates resources in the status bar at the bottom of the user interface.
 * If you use cluster commands at a command prompt to administer a server cluster, the cluster commands do not respond.

Note
 * At least one instance of the Microsoft Distributed Transaction Coordinator (MS DTC) service is affected by this problem.
 * The cluster remains in a functional state, but cannot be managed, even by using the Cluster.exe tool.

MORE INFORMATION
Locking mechanisms are implemented by using single-writer, multi-reader (SWMR) locks. When an SWMR lock is unlocked, it does not synchronize correctly. Therefore, all RPC threads in a process must wait for this lock, and the process cannot be recovered.
