Currently we are connecting OPC DA client to an remote OPC DA server using DCOM technology. OPC DA client can be connected to OPC DA Server. We got all tags from OPC DA Server and the values are good in OPC DA client but we found that there are DCOM errors detected in PC Client's Windows Event Viewer every 2 minutes as long as OPC DA client accesses the OPC DA Server.
I read this article and the error 10036 should be on the PC server side but it's strange that the errors appear on the PC client side.
This is the example error that I got in PC client side, it mentioned the PC client device name but "from [OPC DA Server IP]"
"The server-side authentication level policy does not allow the user [PC Client Device Name\User Name] SID XXXXXX from address [OPC DA Server IP] to activate DCOM server. Please raise the activation authentication level at least to RPC_C_AUTHN_LEVEL_PKT_INTEGRITY in client application."
Could you please suggest how to fix the DCOM error detected in PC Client's Windows Event Viewer? Will the DCOM error affect connection / data transmission between Server and Client (such as causing error in Windows OS Server in the future)? Or we can ignore this error (because the connection between server-client is okay now)?
Thank you
