Problems with application running on Windows 2003

[Manuel Krummenacher]

Hi!

I tried to run an ASP.NET-Application (C#) under Windows 2003. The
application should create an user in Active Directory and give it a
password.

The creation of the user works fine, but in the line setting the password,
this error occurs:

Ein Aufrufziel hat einen Ausnahmefehler verursacht.

System.Reflecti on.TargetInvoca tionException: Ein Aufrufziel hat einen
Ausnahmefehler verursacht. --->
System.Runtime. InteropServices .COMException (0x80072035): Der Server kann

admin.ch\erstel len.aspx.cs:lin e 341

I try to set the password with the following code:

deNewUser.Invok e("SetPassword" , new object[] {"Passwort"} );

(deNewUser is the DirectoryEntry-Object of the user)

The same application works fine under Windows 2000. Both Servers have
Framework 1.1 installed.

Any ideas?

Thanks in advance.
