有关WINNT，必须将值设置为1，而不是0，属性名称是PasswordExpired而不是的pwdLastSet看http://msdn.microsoft.com/en-us/library/aa746542(VS.85).aspx

For WinNT, you must set the value to 1 rather than 0, and the property name is "PasswordExpired" rather than "pwdLastSet"; see http://msdn.microsoft.com/en-us/library/aa746542(VS.85).aspx

在换句话说，对于WINNT这样​​做：

In other words, do this for WinNT:

de.Properties["PasswordExpired"].Value = 1;

（这是混乱的，我知道，但对LDAP你需要的财产的pwdLastSet设置为0，是如何形成的不一致！）

(It is confusing, I know, but for LDAP you need to set the property "pwdLastSet" to 0. How's that for inconsistency!)
