Event Details

Product: Windows Operating System
ID: 4005
Source: Microsoft-Windows-PerfCtrs
Version: 6.1
Message: Failed to load INETMIB1.DLL. Make sure the PATH environment variable contains the DLL. The WIN32 error number is returned in the data.



System Monitor requires the dynamic-link library (DLL) INETMIB1.DLL in order to monitor TCP/IP counters. When you install the TCP/IP protocol using Network and Dial-up Connections in the Control Panel, INETMIB1.DLL is not installed.

To install INETMIB1.DLL:

  1. Insert your installation DVD-ROM in the DVD-ROM drive.
  2. Click Start, click All Programs, and click Accessories.
  3. Right-click Command Prompt, and then click Run as administrator.
  4. At the command prompt, type expand <DVD>:\i386\inetmib1.dl_ %SYSTEM32%\inetmib1.dll and then press ENTER, where <DVD> is the drive letter of your DVD-ROM drive (e.g., D).


You can use Windows Reliability and Performance Monitor to verify that netowkr performance counters are properly collected and displayed in a Performance Monitor graph. In addition, you can use the typeperf command to get a list of the available counters on the local system.

Membership in the local Administrators group is required to complete these procedures.
