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.
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.
When you clone an IaaS node that has MS DTC installed, then both clones use the same unique identifier for MS DTC. Communication between the nodes fails.
