Problems With ReInstall ODBC.I Reely Need HELP!!!

I Use The Win2000 Server And Sql 2000 Server.When I Open My ODBC From The Control Panel,I Get A Massage That The ODBC resource DLL(C:\WINNT\system32\odbcint.dll) Is a different version then The Administrator(C:\WINNT\system32\odbcad.EXE) File,And I Need To ReIinstall The ODBC Components To Ensure A Proper Opertion.When I Click O.K. The ODBC Is Working,But Still,How Do I ReInstall The ODBC Components?
And Will That Instaltion Will Erase My DSN Files,And\Or Other Settings?

Just install the MDAC Latest Version from http://msdn.microsoft.com/library/default.asp?url=/downloads/list/dataaccess.asp
