Hi, I'm trying to set-up a page where a user can change their NT password 
thru ASP.NET and C#. But I can't get it to run without generating 
an "System.Runtime.InteropServices.COMException: Unspecified error" error.

It seems that the Invoke method is generating the error. However, when I 
debug I find in the Locals window that the properties associated with 
DirEntry also report this error, even before the Invoke is attempted. 
Which leads me to believe there is a problem with the initialisation of 
DirEntry.

The basics of the source are;

using System;
using System.DirectoryServices;

namespace WebApp1
{
	public class WebForm1 : System.Web.UI.Page
	{
		public static string currentUser;
	
		public static void ChangePass()
		{
			DirectoryEntry DirEntry;
			DirEntry = new DirectoryEntry(currentUser);
			Object oPassword = new Object[] {"NewPassword05"};
			DirEntry.Invoke("SetPassword", oPassword);
			DirEntry.CommitChanges();

		}

		private void Page_Load(object sender, System.EventArgs e)
		{
			currentUser = Request.ServerVariables["AUTH_USER"];
			// Put user code to initialize the page here
		}
		

		private void Button1_Click(object sender, System.EventArgs 
e)
		{
			ChangePass();
		}
	}
}
		
Any help would be much appreciated!
