Windows reports error 0x80070005 as: General access denied error. Programmers know this error as E_ACCESSDENIED.
This error typically occurs when trying to establish an initial connection with OPC (or DCOM) applications. However, it also occurs while trying to subscribe (setting up OPC advise calls). During this error condition, DCOM was able to find the required (server) application on the target computer, but DCOM permissions prevent users from accessing specific client/server components.
OPC Expert (www.OpcExpert.com) is able to diagnose this problem, so we highly recommend you run it for a thorough check of your system. OPC Expert will provide full repair instructions. OPC Expert also enables users to view OPC server data, connect OPC to Excel, trend values, and more.
