RDT Windows server 2008 r2

The two administrative log-in's that I get under windows 2008 R2 ( We do not use RDT except for administrative  purposes; we do not have and other licenses.)
I have disabled "Deny this  user RDT  privileges ....  " in users properties.  Also 'Administrator' is not in the Remote Desktop User Group.
I have only one user - name  I want to log-in to remote desktop for security purposes,
I cannot seen to 'NOT ALLOW THE USER= ADMINISTRATOR'  to not have  privileges to RDT.
What am I missing?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

you can rename the 'administrator' account.
start/run  secpol.msc
Expand the Security Settings folder, then the Local Policies folder, and then click on the Security Options folder you will see the option to rename the administrator account
Tony DAuthor Commented:
Is there anyway to do this with out changing the administrator account name?
Tony DAuthor Commented:
Again is it anyway locked out the administrator account on Remote Desktop rather than renaming it.
So is administrator Remote Desktop account permanently allowed to login to Remote Desktop?
Thanks again.

You know what administrative purposes are.. it is not for users.. and the user you want to add must be a member of the administors group you have to have users in the local remote desktop users group and the administrator is given access by default and you cannot remove it.
