1、停掉IIS
2、查看IIS 配置数据库密码：
第一步先修改相关文件使查看到的******变为可显示：
在c:\inetpub\adminscripts 找到adsutil.vbs （根据装系统时设定的不同，有的路径可能不一样）
用记事本打开此文件
查找 IsSecureProperty = True （只有一个符合字段，在一个条件语句里面）
将 IsSecureProperty = True 改为 IsSecureProperty = False
保存关闭。
第二步执行查看密码命令：
开始->运行输入cmd回车 打开命令行工具
输入 cd c:\inetpub\adminscripts（进入adminscripts目录，视你机器路径而定）
获取 IWAM 帐户密码命令：cscript.exe adsutil.vbs get w3svc/wamuserpass
你还可以获取 IUSR 帐户密码，我没有用到
命令为：cscript.exe adsutil.vbs get w3svc/anonymoususerpass
输入以上命令，按回车可分别拿到IWAM和IUSR的密码。
3、右键单击 我的电脑->管理，打开计算机管理界面
打开 本地用户和组->用户
右键单击 启动IIS进程帐号 IWAM_**** （注：****一般是计算机名）
点击设置密码，设置为刚才你得到的IWAM密码。
4、更改组件服务中的密码
开始->运行输入cmd回车 打开命令行工具
先输入 cd c:\inetpub\adminscripts
然后输入 cscript.exe synciwam.vbs -v
系统会提示出来一大堆字符，不用管它。关闭窗口然后启动IIS，报错信息应该没有了
