Access Violation Application name : MIBWalk.exe Fault Module name : mswsock.dll

Overview

This article provides brief information on why some Engineer's Toolset tools may not be launching as well as steps to resolve this issue.  

Environment

All versions of Engineer's Toolset

Issue:

Some of the Toolset tools fail to start. For example, MIB Walk fails with the error message: 

Access Violation 
Application name : MIBWalk.exe
Fault Module name : mswsock.dll  

Cause:

MIB Walk tool halts mswsock.dll from initializing. This can happen for Windows 2008 R2 via a Remote Desktop Protocol (RDP) session.

Add the executable that is failing to start, such as MIBWalk.exe, to Data Execution Prevention (DEP) exception. To add an executable to DEP:

  1. Right-click My Computer and select Properties.
  2. In Advanced tab, click Settings in Performance section.
  3. Click the Data Execution Prevention tab.
  4. Select Turn on DEP for all programs and services except those I select.
  5. Click Add and select the executable that is failing to start.
  6. Click OK.
