Unable to connect to ORB in .net windows service was created by rabbi.mathake
Hi there, we have built windows service and we are able to connect to OPC simulation server, OPC Tunneller, but we cant connect to ORB.

we get below error: note service is running on admin account.

[04/25/2023 10:36:03] - DataChangeNotification (PROCESS_CONTRL.771PIC0603_PV_OS *** Type: System.NotSupportedException *** Failure: The COM server does not support the interface 'OpcRcw.Da.IOPCItemProperties'.

This problem could be caused by:
- incorrectly installed proxy/stubs.
- problems with the DCOM security settings.
- a personal firewall (sometimes activated by default).
