Kriege System.Runtime.InteropServices.COMException (0x80004005) nicht weg

[Gast]

Guten Abend,
hier einmal meine Methode:


public void make_new_user(String schema,String entryname)
{

DirectoryEntry dey = new DirectoryEntry(this.protokol +this.paths);
dey.AuthenticationType=AuthenticationTypes.Delegation;
dey.Username=this.name;
dey.Password=this.pass;
DirectoryEntries deys=null;
deys=dey.Children;
// Create a new entry in the container.
DirectoryEntry newrectoryEntry = new DirectoryEntry ();
try
{
newrectoryEntry =deys.Add(entryname, schema);

}
catch(Exception e)
{
Console.WriteLine(e.ToString());
}
}

Vollständige Fehlermeldung:
