I think you may be running registerSTServerNode from the wrong location. You should run it from the console directory under the Domino server's directory. From looking at your output, it would appear that you're running it from the C:\LDAP\console directory instead of the Domino program directory.
Can you send a screenshot or copy of the command window with all of the commands you entered?
