Server2003安装SP2补丁提示密钥无效的解决方法

机器一直没有打SP2的补丁。几天要安装一个程序，还非要SP2不可。没办法。居然打补丁的时候出现了这样的错误信息：

开始找解决的方法，功夫不负有心人。终于找到了答案:

1、新建一个记事本
2、将以下代码拷贝到其中

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion]

"ProductId"="69713-640-9722366-45198"

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]

"CurrentBuild"="1.511.1 () (Obsolete data - do not use)"

"DigitalProductId"=hex:a4,00,00,00,03,00,00,00,36,39,37,31,33,2d,36,34,30,2d,\

39,37,32,32,33,36,36,2d,34,35,31,39,38,00,5a,00,00,00,41,32,32,2d,30,30,30,\

"LicenseInfo"=hex:71,84,c7,56,a0,d6,10,6e,70,b4,9f,e9,10,1a,1e,7a,01,a4,41,09,\

25,20,0e,80,83,80,1f,31,27,86,64,1f,31,dc,22,af,f7,7d,aa,e4,2a,b9,e5,e3,6c,\

e2,01,69,85,70,91,be,a7,9f,95,e5

3、存储成.reg的文件即注册表文件（本来是要把REG文件打包发上来，但是目前百度空间还好像不支持）
4、然后双击运行它就自动导入到了注册表中了
这次在安装SP2 就没有任何问题了 。
