Error in Manager Service Communication
IaaS nodes that are cloned from a template on which MS DTC is installed contain duplicate identifiers for
MS DTC, which prevents communication among the nodes.
Problem
The IaaS Manager Service fails and displays the following error in the manager service log.
Communication with the underlying transaction manager has failed. --->
System.Runtime.InteropServices.COMException: The MSDTC transaction manager was
unable to pull the transaction from the source transaction manager due to
communication problems. Possible causes are: a firewall is present and it
doesn't have an exception for the MSDTC process, the two machines cannot
find each other by their NetBIOS names, or the support for network transactions
is not enabled for one of the two transaction managers.
