OPC server specifies the user account that should be used when COM starts up the process The available settings are different for servers that run as local executables as opposed to those that run as NT services Note It is strongly recommended that OPC servers should be installed to run as NT services if they are going to be accessed by A remote clients via DCOM This ensures that the server can always be accessed even if no one is presently logged on to the machine and only one server process ever starts up It also adds a greater degree of security in terms of who is able to shut down the server process Servers that run as local executables have the option of running as the launching user the calling client this is the default the interactive user the one currently logged onto the machine or a specified user It is usually best to use the interactive user or a specified user Otherwise remote clients might start up multiple separate server processes that are not accessible to others Servers that run as NT services should generally run as the local System account Alternatively the server can be set to run as a specified user although this is usually done from the Service Control Manager applet rather than DCOMCNFG Access and Launch permissions are particularly important when installing a server to run as an NT service Default Protocols The Default Protocols tab specifies the communication protocols available to DCOM The order
