问题描述

我们已经编写了一个使用WCF的VS 2012程序.它正在使用net.tcp绑定.该程序充当客户端，从OPC服务器读取数据并将其发送回应用程序服务器.当此应用程序在许多地方运行时，我面临着一个特殊的问题 在其中一种安装方式中

问题是

1.启动服务后，应用程序运行正常.

1. Application runs perfectly fine when we start the service.

2.一段时间后，应用程序给出诸如"CoCreateInstanceEx的错误":由于所配置的身份不正确，服务器进程无法启动.检查用户名和密码."

2. After some time the application gives error like "CoCreateInstanceEx: The server process could not be started because the configured identity is incorrect. Check the username and password."

没有固定的时间.有时，客户端会连续运行三天，有时甚至无法运行一小时.

there is no fixed time. some times client runs for 3 days continuously and sometimes it doesn't run for an hour .

3.当我们使用mstsc远程登录PC时，上述异常消失，客户端应用程序再次开始正常工作.

3. when we login into the PC remotely using mstsc, the above exception goes away and client application again starts working normal.

4.该应用程序已安装在Windows 7 Professional中.

4. the application is installed in windows 7 professional .

我们已尝试通过Google进行许多设置更改，但仍然不成功.

we have tried many setting changes by google, but still we are not successful.
