In the distributed system manager (DSM) I can see that the local OPC1/NI OPC Client Status is Active=true, Connected=false.
When I enable diagnostics I get HRESULT=0x80070005 Access is denied.
| |-GetCLSID: ProgID=National Instruments.NIOPCServers.V5, Machine="", CLSID=0-0-0-00-000000 (FAILED, HRESULT=0x80070005 Access is denied. )
I have been playing with the settings for both Component Services/DCOM and Services/NI OPC server & NI OPC server AE. People say that I should "run as interatice user". That is now available, greyed out for some reason. I suceeded to set a named local user for both Component/DCOM and Services/NI OPC, but no improvement. Also a working setup on another PC has both users as system=default.
Any ideas?
