OPC Server-specific DCOM Settings

OPC HDA server-specific COM/DCOM settings are supported on all Windows operating systems. You must change the OPC HDA server settings so remote users can access the OPC HDA server as an OPC Data Access Server. It is recommended that all users requiring access to remote OPC HDA servers be members of the Administrators group.

Important: Since the Everyonegroup includes all authenticated users, it is recommended to add these permissions to a smaller subset of users. It is recommended that you create a group to contain individual users that need to access remote OPC HDA Servers. It is also recommended that all users who require access to remote OPC HDA Servers be members of the Administrators group.
