Cannot Connect with the OPC Quick Client when Running LinkMaster as a Service

Last Update: 11/12/2018

When running as a service, LinkMaster either runs under the default System User account or under a specified user logon account that may or may not be the one that the user is currently logged in with. Furthermore, the DCOM security settings must be properly configured in order to establish local or remote connections. For more information on properly configuring DCOM, refer to Remote OPC DA Quick Start Guide (DCOM). For information on more detailed settings, refer to DCOM - Secure by Default.
