How to Fix dhcpsapi.dll Errors Without Downloading

Do not download this file from third-party DLL websites. Those files often contain malware, are outdated, or can cause system instability. Use these safe, built-in Windows tools instead.

1. Run the System File Checker (SFC)

This tool scans all protected system files and replaces corrupted or missing ones with a cached copy.

  1. Press the Windows Key.
  2. Type cmd.
  3. Right-click Command Prompt.
  4. Select Run as administrator.
  5. Type sfc /scannow and press Enter.
  6. Wait for the scan to finish.
  7. Restart your computer.

2. Run the DISM Tool

If the SFC tool cannot fix the file, use the Deployment Image Servicing and Management (DISM) tool to repair the underlying Windows system image.

  1. Open Command Prompt as an administrator.
  2. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
  3. Wait for the process to complete (this may take 10-15 minutes).
  4. Run sfc /scannow one more time after DISM finishes.
  5. Restart your computer.

3. Enable the DHCP Server Feature

If you are on Windows Server and the file is completely missing, the DHCP Server role might not be installed correctly.

  1. Open Server Manager.
  2. Click Manage in the top right.
  3. Select Add Roles and Features.
  4. Advance to the Server Roles section.
  5. Check DHCP Server (or re-install it if it is corrupted).
  6. Complete the wizard and restart the server.

4. Check the Recycle Bin
