Windows - Local User Management

I am trying to implement a script/utility that renames a user, sets a default password, and then will prompt the user to change their password on their initial logon in Windows Server 2003. I am able to accomplish the first 2 items but not the third. Specifically, I want the user to encounter the Windows dialog box that states the following :"you are required to change your password at first logon" Then it takes them to the "Change Password" dialog box which has an OK and Cancel button. If they hit cancel, they are taken to the initial login screen.

I implemented the code below to try to accomplish this. The behavior I am getting instead is that the user is given a dialog box that states that the password has expired and must changed, is prompted to do so. However, the user can simply click Cancel, and the user is logged in. The utility is scripted in c# but I am open to another language if it makes things easier.

DirectoryEntry directory = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");
Directo开发者_开发技巧ryEntry userEntry = directory.Children.Find("defaultUsername"); 
userEntry.Rename("theUser");
userEntry.Invoke("SetPassword", new object[] { "defaultPassword" });
userEntry.Properties["PasswordExpired"].Value = 1; 
userEntry.Properties["UserFlags"].Value = 0x800201; 
userEntry.CommitChanges();

You can't use UserFlags 0x800000 to set a password as expired - see here. Using PasswordExpired = 1 should be sufficient. Did you try this with UserFlags = 0x201?

userEntry.Properties["PasswordExpired"].Value = 0;

I think thats the issue
