Implementation Scope：

本文档将说明Windows FaxService莫名其妙地不在服务列表中显示，而且手工注册faxsvc.exe也不行。本文档介绍了一种巧妙的招数恢复它。

适用操作系统：Windows 2000 Advanced Server(SP4)

现象

由于需要调用Windows自带的FaxServer虚拟打印功能，我们需要在一台服务器上调用FaxServer的COM组件。

在服务器A上，我们很容易就找到了FaxService服务，它的信息如下：

Description:  帮助您发送和接收传真

Path:        C:/WINNT/system32/faxsvc.exe

但是，在服务器B上，服务列表中却没有这个服务。对比了两台服务器的system32路径下的传真相关文件，一模一样。手工在B上运行faxsvc –service命令，也没有效果。

没有这个FaxSvc服务，我们就无法进行虚拟打印。调用

pFaxSvr.CreateInstance(__uuidof(FaxServer)

时就会失败。

那到底差在哪儿呢？什么导致服务无法注册，而且没有任何错误报告呢？

 

这时候，如果运行B服务器的%systemroot%/system32目录下的faxserv.msc控制台文件，将会得到这个错误报告：

Impossible to estabilsh a connection with the fax service management. it's possible the fax service management is not running or the computer name is wrong

解决步骤

按照我的这个步骤做，你就一切Okay了。

从已经有FaxSvc服务的正常机器上，导出注册表项

HKEY_LOCAL_MACHINE/

SYSTEM/

CurrentControlSet/

Services/

Fax

然后在服务器B的注册表中导入这一项。

 

或者你直接把下面表格中的文字保存为“faxsvc.reg”，直接运行即可。

确认输入注册表成功之后，重新启动服务器。这时候，Fax Service就在服务列表中出现了。你也可以正常调用它了。

只不过这种方式搞出来的faxsvc，察看服务属性时，会蹦出一个错误对话框“配置管理器：指定的设备实例句柄和目前设备不一致。”：

 

 

 

不过不影响使用。

总结：

A novice asked the master: "I have a program that sometimes runs and sometimes aborts. I have followed the rules of programming, yet I am totally baffled. What is the reason for this?"
一个初学者问大师：“我的一个程序有时正常有时不正常。我已经完全遵循编程的规则，而且我完全被它弄糊涂了，到底是什么原因会导致这样呢？”
The master replied: "You are confused because you do not understand the Tao. Only a fool expects rational behavior from his fellow humans. Why do you expect it from a machine that humans have constructed? Computers simulate determinism; only the Tao is perfect.
大师说：“你困惑是因为你不了解道。只有傻瓜才会相信只要遵循别人所说就能得到想当然的结果。为什么你要从一个人类自己构造的机器中去得到想当然的结果呢？计算机只是决定论的产物；只有道才是唯一完美的。

The rules of programming are transitory; only the Tao is eternal. Therefore you must contemplate the Tao before you receive enlightenment."
任何编程的规则都只适合于特定的情况，只有道才是永恒不变的。所以在你受到指引之前要先去思考道。”

"But how will I know when I have received enlightenment?" asked the novice.
“但是我怎么知道我何时受到指引呢？”

"Your program will then run correctly," replied the master.
“当你的程序正确运行时”。大师说。
