.Net framework 3.5 无法安装，附解决方法
下载了VS2008,结果在安装时总是失败，检查日志，提示：

采用过的办法有：
1）
/CuteNet/archive/2007/11/22/
2）
./blog/static/47554362008217104214573/
3）还有其他的一些办法，都不行
最后是怎么解决的，连我也不敢相信：
更改机器名 就OK了
解决过程：
1）我用电脑A的ghost文件在电脑B上反ghost
2）由于反ghost后电脑B的机器名和IP都与电脑A一样，故更改机器名和IP
3）然后想，电脑B是否可以安装呢？马上测试一下，居然OK了，大喜，看来修改机器名可以解决该问题
4）修改电脑A的机器名，安装vs2008，也OK了，折腾了我两天的问题终于解决
