MSDTC failed in windows cluster any idea?
Solution 1:
Try deleting the MSDTC resource, enabling network DTC access in both nodes and creating the resource again.
What are you using as storage for MSDTC?
Are there errors in the Windows Event Log after the failed attempts to bring the resource online? What do they say?
Solution 2:
The account using the FTC has to have full control on the cluster. Read on windows 2008; right click the cluster in cluster manager and select properties
