Machine Requests Fail When Remote Transactions Are Disabled
Machine requests fail when Microsoft Distributed Transaction Coordinator (DTC) remote transactions are
disabled on Windows server machines.
Problem
If you provision a machine when remote transactions are disabled on the Model Manager portal or the
SQL Server, the request will not complete. Data collection fails and the machine request remains in a
state of CloneWorkflow.
Cause
DTC Remote Transactions are disabled in the IaaS SQL Instance used by the vRealize Automation
system.
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.
Note Ensure that all Windows servers have unique SIDs for MSDTC configuration.
In addition, the IaaS Manager Service host must be able to resolve the NETBIOS name of the IaaS
SQL Server database host. If it cannot resolve the NETBIOS name, add the SQL Server NETBIOS
name to the Manager Service machine /etc/hosts file and restart the Manager Service.
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 field for the DTC Logon Account.
