There are just too many possibilities of ntdll.dll error.
Check the Windows service pack level you're running and then check Microsoft's support site to see if there is a more recent service pack available for installation. Some issues that caused ntdll.dll errors have been corrected in these service packs from Microsoft.
Update drivers for any hardware in your computer where updated drivers are available. Outdated drivers sometimes cause ntdll.dll errors.
Test your memory for damage. If you're receiving ntdll.dll messages, one possible cause could be a bad memory module in your system. Testing your memory will either identify a problem or clear your RAM of any responsibility.
Replace your memory if it fails any of your tests.
Ntdll.dll errors could occur if you have an Iomega Zip drive on the same IDE cable as the hard drive inside your computer. If so, move the Zip drive to a dedicated IDE controller.
Replace the IDE cable connecting the hard drive to the motherboard. If this cable is damaged or malfunctioning, one symptom could be the ntdll.dll error you're seeing.
Repair your installation of Windows. If individual software reinstallations fail to resolve the problem, a repair installation of Windows will replace the ntdll.dll file.  (You have done that)
While extremely rare, if everything else has failed, including the clean installation from the last step, you could be dealing with a hardware issue with your hard drive.
Reinstall iTunes if the ntdll.dll error only displays when you use only this program.
