Please note: not all possible combinations of setting these two levels make sense.
Known Bugs: on Windows 2000 operating systems the Network Configuration Icon disapears when setting
DCOM security levels to None and Anonymous . The network still works but the IP-Address of the NIC can
not be changed anymore. Change temporarely to default settings to change IP Address or use None and
Delegate .
• On the Default COM Security Tab the Access- and Launch permission for all COM-Objects can be
changed. As the OPC Client is nothing else than a COM Client, the security setings should be changed
to grant access to the Client application. Specially when the OPC Server sends callbacks (e.g.
OnDataChange) to the OPC Client the server's process must have access permission on the Client.
◦ The Default Access Permission should be granted for
Administrators
Interactive User
System
Network
"OPC Server's Security Context"
• The Default Launch Permission should not be changed on the Client machine.
