在安装的时候出现一个错误提示“安装程序无法复制文件CONVLOG.EX_”，上网找了很多资料，都说是因为版本问题，考虑到自己的服务器安装的是2003 SP1，后来打了补丁到SP2的，也就认为是版本问题，结果下了很多SP2版本也不行，再到网上搜索。有个说法是在运行－中输入“esentutl /p %windir%/security/database/secedit.sdb ” 就可以了，试了一下，还真管用，虽然不知道什么原理，但还是把它记录下来吧，以后用！
C:\Documents and Settings\Administrator>esentutl /p %windir%/security/database/s
ecedit.sdb

然后就可以顺利安装IIS6了
另一篇：
IIS出了点问题，就重新安装。于是在安装IIS时如果老提示无法复制convlog.exe、iisadmin.mfl等文件。
在网上搜一堆，说是因为损坏了系统内部数据库所致.修复损坏的数据文件即可正常安装。
解决方法如下(开始 > 运行 > 输入 CMD >再输入以下命令):
1、esentutl /g %windir%/security/database/secedit.sdb （该命令参数用于查询secedit.sdb文件是否被损坏）
2、esentutl /p %windir%/security/database/secedit.sdb (修复secedit.sdb文件)
这样convlog.exe是可以安装了，但到了iisadmin.mfl无法找到。点浏览 > C:\WINDOWS\ServicePackFiles\i386 ，导航到这个文件夹下，再点确定，就可以安装了！
