HRESULT: 0x80070005 (E_ACCESSDENIED) while trying to connect to controller
in RobotStudio
Hi,
I'm getting an error while trying to connect to any controller (have tried 2 different ones so far):
- Win7 SP1 x64, using Robot Studio 6.05 SP1 (first use, just installed, tried x64 and x86 version, with admin rights, firewall configuration...)
- Direct Connection to the respective controller via the LAN service port
- Controller is listed as available, RobotStudio 5.12.04 (the other one had a different version)
- When trying to connect I get 3 different errors (when trying to connect multiple times)

- after the second error, the program crashes after a certain amount of time due to instability
any suggestion on solving this issue?
Best regards

Are the robot communication services running (RobComCtrlServer and RobNetScanHost)?Johannes Weiman

Yes, both are set to manual startup and are running at the moment0

Hi Bastian,
For the first error:
RobotStudio .NET exception: Zugriff verweigert (Ausnahme von HRESULT: 0x80070005 (E_ACCESSDENIED))
is simply that you don't have access eather you are not admin on the pc or miss permision.
For the second error:
RobotStudio .NET exception: Der Remoteprozeduraufruf ist fehlgeschlagen. (Ausnahme von HRESULT: 0x800706BE)
How does it work using direct connect to the service port? If the direct connection works but the LAN connect does not then it looks like a security limitations error. This could be caused in many ways, with these being the most common:
1. FireWall
2. Port blocking
3. Remote Procedure call blockingFor the firewall you could set up exceptions for the [RobComCtrlServer] and [RobNetScanHost] processes. Their service names are [ABB Industrial Robot Communication Server] and [ABB Industrial Robot Discovery Server] respectively.
If they are blocking ports they check the ports list.
If they are blocking [Remote Procedure Call] there is usually a setting in the firewall.For the third error:
RobotStudio .NET exception: Der RPC-Server ist nicht verfügbar. (Ausnahme von HRESULT: 0x800706BA)
I think the problem is due to the NetScan process not being shut down correctly. Before trying to connect the controller, start TaskManager and shut down "RobNetScanHost.exe" and "RobComCtrlServer.exe". You may need to click "show processes from all users" in order to see them.
Hopefully it helps!!

Thank you for the input, Adnan.
The services are started as local system and I have started the RobotStudio with admin rights.
Firewall rules are set for incoming and outgoing traffic on all ports for both services.
As the detection of the controller works, I think the RobNetScanHost works correctly (and it stops working throwing RPC errors if I restart the service while RobotStudio is active).
My interpretation would be, as the errors always come in consecutive order:
1. CreateRobComCtrlServer does crash somehow due to missing rights or some interference with other programs or services (which may block ports/files/resources)
2. IRobComCtrlServer2.Connect does not work, as the instance of RobComCtrlServer created during error 1 is corrupted
3. - x. CreateRobComCtrlServer can not be called anymore as the service has lost connection to the program
If I restart the RobComCtrlServer service after starting RobotStudio but before connecting, I will "only" get the RPC-Error without any crashing (which led to my interpretaton of error 3)
My main question would be:
what causes the first crash at the first call of CreateRobComCtrlServer? I've tried to remote debug RobotStudio with Visual Studio 2012, but didn't get any reaction.
Edit: I've ran some "netstat" and none of the ports I've found in the port forwarding recommendations is already being listened...0 -
Same PC, virtual machine with clean Win7 x64 installation:
No errors at all...
