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).
