It allows applications to scan, discover, and map InfiniBand network topologies.

Standard File Location

The file is commonly located in the installation directory of the specific networking software or software development kit (SDK) utilizing it, or system directories if registered globally:

C:\Program Files (x86)\Mellanox\MLNX VPI\IB\bin\ (or similar driver paths)

Inside the root folder of the specific application throwing the error.

How to Fix the Error Without Downloading the DLL

Downloading individual DLL files from third-party websites is unsafe and can introduce malware. Instead, use these clean methods to repair the file:

1. Reinstall or Repair the Driver Stack

Since this file belongs to network stack software, repairing the parent program is the most effective solution.

Open Settings (Win + I) and go to Apps > Installed apps.
Look for Mellanox VPI, WinOF, OpenFabrics Windows Openib, or related network driver software.
Click the three dots, select Modify or Uninstall, and choose Repair.
If no repair option exists, uninstall the program, restart your PC, and run the official installer package you originally used.

2. Run Windows System File Checker (SFC)

If the file was placed in system directories by Windows, built-in tools can fix it.

Press the Windows Key, type cmd, right-click Command Prompt, and select Run as administrator.
Type the following command and press Enter:
```
sfc /scannow
```
Wait for the scan to finish and restart your computer.

3. Restore from the Recycle Bin

If you accidentally deleted the file recently, it might still be recoverable.

Open the Recycle Bin on your desktop.
Search for libibnetdisc32.dll using the top-right search bar.
Right-click the file and select Restore.

4. Re-register the DLL File

If the file exists but the system cannot detect it, you can manually re-register it via the command line.

Open Command Prompt as an administrator.
Type the following command and press Enter:
```
regsvr32 /u libibnetdisc32.dll
```
Then, type the following command to re-register it:
