I try to explain better.. With my application i can create user and store it to active directory. I set for the user a default password. With this credentials user can login into Windows: if it's the first access, Windows ask to change the password. If a user losts the password, my application allow to reset it, and set a new default password. Now when the user login into Windows, the system have to re-ask to change the password... How can I do this? The code to reset the password is below DirectoryEntry uEntry = GetDirectoryEntry(Path); uEntry.Invoke("SetPassword", new object[] { "NewPassword"}); uEntry.Properties["LockOutTime"].Value = 0; //unlock account int flags = (int)uEntry.Properties["userAccountControl"][0]; uEntry.Properties["pwdLastSet"].Value = -1; uEntry.CommitChanges(); uEntry.Close();

I made an application with asp.net 2.0 (c#) to manage users in active directory. I need to reset the user's password and at the first access The system have to ask me to change the password. Any Idea?
