Replied by support on topic Unable to Connect ORB in .Net Service
Hello,
I have some questions.

1. I am making an assumption that by "ORB", you mean MatrikonOPC Redundancy Broker. Is that correct?
2. Which version of the ORB are you using?
3. Which version of QuickOPC are you using?
4. Is you project targeting .NET Framework, .NET Core, or .NET 6+?

Thank you

Unable to Connect ORB in .Net Service was created by Jannie@Moore
Hi there, we have build windows service in .net, we can connect to Simulation Server , We can connect to Tunneller.

But we cannot connect to ORB.

We get below error

[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).
