What are dpnathlp.dll Error Messages?


Dynamic Link Library dpnathlp.dll Errors

dpnathlp.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like dpnathlp.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like dpnsvr.exe - to follow. These files were created so that multiple programs (eg. Stronghold) could share the same dpnathlp.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when dpnathlp.dll is attempted to be loaded either when Stronghold is starting up, or in some cases already running. Some of the most common dpnathlp.dll errors include:

Your dpnathlp.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Stronghold), or deleted by a malware infection. Furthermore, dpnathlp.dll file corruption could be caused from a power outage when loading Stronghold, system crash while loading dpnathlp.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix dpnathlp.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your dpnathlp.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the dpnathlp.dll error, please proceed to the Step 2 below.

Step 2: If recently installed Stronghold (or related software), uninstall then try reinstalling Stronghold software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many dpnathlp.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the dpnathlp.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.
