本文档根据各种不同的情况，讲述如何进行OPC DCOM配置。

　　 对于远程访问OPC服务器，需要在客户和服务器计算机上都进行DCOM设置，以前我们采用的方式是： 客户、服务器都建立一个名字、密码相同的具有管理员权限的帐号，并分别以次登录，在服务器端将OPC服务器的启动方式设为交互式用户。这种方法虽然方便，但安全性较差，不利于在实际应用中推广。这里提供一些较合理的解决方案。（假定都是在工作组里）

-This document is based on a variety of different situations, about how OPC DCOM configuration. OPC server for remote access, you need both client and server computers for DCOM settings, we used the approach are: client, server have established a name, password, the same account with administrator privileges, and were an inferior race log in server will set the OPC server is started interactive user. This method is convenient, but less secure, is not conducive to the promotion of practical applications. Here are some of the more reasonable solution. (Assuming all in the Working Group)
