Thank you John. I suspect this issue could be related to a Norton Antivirus, Firewall and Network monitoring which is interfering with DTC communication. When the main SC instance is being started it is treated as a single task of SierraChart.exe that spawns new instances. Because I have the entire Sierra Chart installation folder excluded from Norton firewall checks and attack threats it has no issue starting the main instance and sub-instances. However, when main SC instance stops communicating with sub-instances because it's busy calculating and loading charts any new outside activity from sub-instance is being identified and treated as a threat by Norton. I have vetted and excluded the SierraChart.exe and SierraChart_64.exe executables from each sub-instance subfolder by telling Norton Firewall and Monitoring to ignore it and the problem has gone away - once the main instance finished load of the chartbook the connection to sub-instances is successfully re-established.
