18 DCOM Settings with the dcomcnfg System Program

It is advisable to register other OPC clients as DCOM objects. The advantage of this is that you can configure the security settings as described here with DCOMCNFG without needing to modify system- wide settings.

Security Settings per User Program

You can also make the settings described in the earlier sections using the user program. To do this, you use the“CoIntializeSecurity ( )” call from the Windows programming interface with which you can specify the DCOM security.

Notice

Remember that the security settings made in the user program have priority over the settings made in the DCOM dialog!
