org.jinterop.dcom.common.JIException: The object name is not found [0xC0000034]

I am having a problem using “J-INTEROP” trying to make an OPC DA client for andriod devices.

I made all the DCOM configurations and today I can connect to the server from any PC that is within my network regardless of the user that connects.

The error that is throwing me is: org.jinterop.dcom.common.JIException: The object name is not found [0xC0000034]

The OPC DA server I am using is KepServerEX.V4

The error occurs in the following line: val comServer = JIComServer(JIProgId.valueOf(“KEPware.KEPServerEx.V4”), “192.168.1.11”, session)

                }


            } catch (e: UnknownHostException) {
                e.printStackTrace()

                }
            }
 }).start()


    }

I did a lot of testing on the DCOM setup. Assuming a problem with some windows permission, for these tests I am using Windows 10. And the tests are with real andriod devices.

I also did tests with different OPC DA clients for windows and the communication with the server works correctly for me.
