set ODBC entry for all users in WTSRV?

Hi, I need to set a DSN entry in ODBC on a .mdb database for all the users that connect on my Terminal Server. I set the ODBC with the administrator account but when a normal user log on terminal, he don’t keep the DSN entry and cannot connect to the database. When I give the user administrator’s rights, everything works fine but when I downgrade him to normal user, The ODBC entry exists no more.How can I set an ODBC entry that will be available for administrators and normal users?
