To Depository Trust Company Participants:

     We are enclosing herewith the material listed below relating to the offer
by NCR Corporation, a Maryland corporation (the "Company"), to exchange its

the Company's Prospectus, dated April 10, 2003, and the related Letter of

               hold Outstanding Notes in your name or in the name of your
               nominee, with space provided for obtaining such client's

                                                                 NCR CORPORATION
