ASP.NET方式在工作组内修改帐户密码
背景：
以工作组的方式在服务器A上架设了TFS2008，分配给组员的帐户是服务器A的本地帐户，在这种情况下，组员如果想要修改密码，就需要提供一个修改的平台。
首先想到的是，在TFS的Sharepoint门户上集成修改密码的页面，但是很遗憾，在网上找到的Web part控件都有些问题，实在不行了，就只好自己单独弄了一个ASP.NET页面，其实还是使用DirectoryEntry来使用修改。修改密码的命令有"ChangePassword"和"SetPassword"，这两个命令的区别在于：
"ChangePassword"需要旧密码，它对于修改密码的帐户没有要求。
"SetPassword"不需要旧密码，但它要求被修改的用户拥有管理员权限。
最后选择使用ChangePassword，码如下：
