SYMPTOMS
When a clustered system is running a workload with many Microsoft Distributed Transaction Coordinator (MS DTC) transactions between multiple SQL Servers in the cluster, if one of the virtual servers moves from one node to another, the Remote Procedure Call (RPC) connection to the server may not always end.

As a result, MS DTC assumes that two SQL Servers with the same globally unique identifier (GUID) are trying to connect to the same MS DTC. This causes SQL Server to fail to connect to MS DTC, and an event with the error message &quot;Failed to Enlist&quot; is logged in the event log. In some cases, the databases cannot recover from failover.

The following error messages are logged in the SQL log:

server Attempting to initialize Distributed Transaction Coordinator.

server Resource Manager Creation Failed: Result Code = 0x8004d102
