File Description: libibverbs.dll

Overview

libibverbs.dll is a dynamic link library file associated with RDMA (Remote Direct Memory Access) technology. It is the Windows port of the Linux libibverbs library, which provides the user-space verbs API for InfiniBand, RoCE (RDMA over Converged Ethernet), and iWARP network fabrics.

Key Details

  • Description: RDMA Core Verbs Library
  • Common Use: High-performance computing (HPC), database clusters, network-intensive applications, and MPI (Message Passing Interface) programming.
  • Standard File Location:
    • C:\Windows\System32 (on 64-bit systems for 64-bit applications)
    • C:\Windows\SysWOW64 (on 64-bit systems for 32-bit applications)
    • Inside specific application folders utilizing RDMA (e.g., Microsoft MPI, specialized network drivers, or cluster software).

How to Fix libibverbs.dll Errors Without Downloading

If you receive an error stating that libibverbs.dll is missing, corrupted, or not found, you do not need to download questionable standalone DLL files from third-party websites. Instead, use these native and secure methods to restore the file.

1. Enable or Reinstall Windows Feature (Containers / WSL)

This library is frequently used by the Windows Subsystem for Linux (WSL) and Windows Containers for high-speed networking.

  • Open the Start Menu, type Turn Windows features on or off, and press Enter.
  • Locate Containers and Windows Subsystem for Linux.
  • Uncheck them, click OK, and restart your computer to remove them.
  • Re-open the same menu, re-check both features, click OK, and restart again to cleanly reinstall the associated files.

2. Run SFC and DISM Tools

Windows has built-in utilities to repair corrupted operating system files automatically using the local system image cache.

  • Right-click the Start button and select Terminal (Admin) or Command Prompt (Admin).
  • Run the Deployment Image Servicing tool first by typing: DISM.exe /Online /Cleanup-image /Restorehealth
  • Press Enter and wait for the process to complete.
  • Run the System File Checker by typing: sfc /scannow
  • Press Enter, let the scan finish, and restart your PC.

3. Reinstall Network Driver Frameworks

Since this file belongs to the RDMA core architecture, reinstalling your high-performance network adapter software will regenerate it.

  • If you use Mellanox/Nvidia hardware, open Settings > Apps > Installed apps.
  • Locate and uninstall the WinOF or WinOF-2 driver packages.
  • If you use Microsoft MPI (Message Passing Interface), uninstall it from the same menu.
  • Restart your computer. Windows will reinstall the base drivers automatically, or you can run your existing official local installer package.

4. Check the Recycle Bin

If the file was accidentally deleted by you or your security software, it might still be on your local drive.

  • Open the Recycle Bin on your desktop.
  • Search for libibverbs.dll.
  • If found, right-click the file and choose Restore.
