Solution
1 Launch Windows Server Manager to enable DTC on all vRealize servers and associated SQL servers.
In Windows 7, navigate Start > Administrative Tools > Component Services.
N Ensure that all Windows servers have unique SIDs for MSDTC conguration.
2 Open all nodes to locate the local DTC, or the clustered DTC if using a clustered system.
Navigate Component Services > Computers > My Computer > Distributed Transaction Coordinator.
3 Right click on the local or clustered DTC and select Properties.
4 Click the Security tab.
5 Select the Network DTC Access option.
6 Select the Allow Remote Client and Allow Remote Administration options.
7 Select the Allow Inbound and Allow Outbound options.
8 Enter or select NT AUTHORITY\Network Service in the Account eld for the DTC Logon Account.
9 Click OK.
10 Remove machines that are stuck in the Clone Workow state.
a Log in to the vRealize Automation appliance.

b Navigate to Infrastructure > Managed Machines.
c Right click on the target machine.
d Select Delete to remove the machine.
Error in Manager Service Communication
IaaS nodes that are cloned from a template on which MS DTC is installed contain duplicate identiers 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.
Cause
When you clone an IaaS node that has MS DTC installed, then both clones use the same unique identier for
MS DTC. Communication between the nodes fails.
Solution
1 Open an Administrator command prompt.
2 Run the following command: msdtc -uninstall
3 Reboot the virtual machine.
