How to resolve Ntdll.dll error?

SYMPTOMS

Ntdll.dll errors can be caused by a number of different things which result in many different error messages:

• "STOP: 0xC0000221 unknown hard error C:\Winnt\System32\Ntdll.dll"
• "STOP: C0000221 unknown hard error \SystemRoot\System32\ntdll.dll"
• "AppName: [PROGRAM NAME] ModName: ntdll.dll"
• "[PROGRAM NAME] caused a fault in module NTDLL.DLL at [ANY ADDRESS]"

Cause

The causes of ntdll.dll error messages can vary greatly. However, most ntdll.dll errors result from a corrupt or damaged version of the ntdll.dll file itself, corrupt hardware drivers, or issues between Windows and other programs.

Resolution

Method 1

If the ntdll.dll error only displays when you use a specific software program, uninstall the program, reboot your computer, and then install the latest version again from scratch.

Note:If the software program has any updates or service packs available, install them too. The software's programmers may have identified an issue with the program that caused the ntdll.dll error and then issued a patch for it.


Method 2

Selectively disable Internet Explorer add-ons. If your ntdll.dll error is displaying when you start, run, or close Internet Explorer, an add-on may be causing the problem. Disabling each add-on, one by one, will determine which add-on is the culprit (if any).

Method 3

Perform a repair installation of Windows XP. If individual software reinstallations fail to resolve the problem, a repair installation of Windows will replace the ntdll.dll file. Remember to install all Windows service packs and other patches after this installation.

Method 4

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.
