AzeoTech Posted March 16, 2020 Share Posted March 16, 2020 Either DCOM isn't setup correctly on the OPC server computer, or RSLinx has security settings that are blocking remote connections. Quote Link to comment Share on other sites More sharing options...
YamidP Posted March 16, 2020 Author Share Posted March 16, 2020 What DCOM configuration do you recommend for the client and server? Quote Link to comment Share on other sites More sharing options...
AzeoTech Posted March 16, 2020 Share Posted March 16, 2020 The client doesn't need any special DCOM configuration. The server is the one that has to be setup. You also may need to double check any firewalls, including the software firewall. And double check that you enabled all users on the server.
