reset user password

Question

I have a server which has machines...

I have an administrator and multiple users... these are all windows users and not present in the databse.

How do i reset the user password.... i log in using the administrator and provide the username that needs to be reset..

I tried

 string newPassword;

 u = Membership.GetUser(UsernameTextBox.Text, false);

but this does not work...

any suggestions... thanks

Code to add users:

 DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
            DirectoryEntry NewUser = AD.Children.Add(username, "user");
            NewUser.Invoke("SetPassword", new object[] { password });
            NewUser.Invoke("Put", new object[] { "Description", description });
            NewUser.CommitChanges();

Answer 1

try this

string username = "user";
string password = "newpassword";
MembershipUser mu = Membership.GetUser(username);
mu.ChangePassword(mu.ResetPassword(), password);

if you have in your web.config requiresQuestionAnswer="true", you will get an error when you try and reset the password.

Answer 2

You are probably looking for the ResetPassword method. To reset to a known password you can use something like this:

MembershipUser currentUser = Membership.GetUser(user_name);
bool bPasswordChanged = false;
bPasswordChanged = currentUser.ChangePassword(currentUser.ResetPassword(), new_password);

I got it done by this methid.. it works thanks for the answers though`

           DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
            DirectoryEntry HostedUser = AD.Children.Find(hostedUserName, "user");

            string password = new HostedGuiAddMachines().CreateRandomPassword(8);
            HostedUser.Invoke("SetPassword", new object[] { password });
            HostedUser.Close();
            AD.Close();
