    The RPC server is unavailable


    Hi



    I'm working on an OPC DA application which use DCOM.

    Since the windows 10 update 1903, my OPC DA client cannot more connect to the server this worked well with the 1803.

    Here is the obtained error message:



    "The RPC server is unavailable. Please check if the COM server is up and running and that route to the COM Server is accessible A simple "Ping" to the Server machine would do. Also please confirm if the Windows Firewall is not blocking DCOM access. [0x800706BA]"



    After analysis, the failure occurs at a DCERPC Advise request on a IConnectionPoint opnum=5.



    Some precisions:

    - the issue occurs when the OPC DA Server is in localhost or in remote host.

    - the issue occurs also when Windows Defender is deactivated.

    - the services rpcss and RpcEptMapper are correctly running.



    Any suggestion ?



    Regards

    :)

    Where do you back to?

    RPC server unavailable means the network connection that you use is not available and this can be for many reasons.

    See link below explaining further what i mean.
