SYMPTOMS
When you attempt to send or receive an e-mail message using Outlook Express, you may receive the following error message:

MSIMN caused an invalid page fault in module INETCOMM.DLL at.



CAUSE
This error message can occur if you install the Windows Sockets (Winsock) 2 Update, but do not update Transmission Control Protocol/Internet Protocol (TCP/IP) using the Vipup20.exe and Vtcpup20.exe files.

This error message also occurs if you install Microsoft Personal Web Server 4.0 from the Microsoft Windows NT 4.0 Option Pack. This version of Personal Web Server 4.0 includes the Winsock 2 Update.



RESOLUTION
To resolve this behavior, download and install the Vipup20.exe and Vtcpup20.exe files from the Microsoft Download Center.

The following files are available for download from the Microsoft Download Center:

Download Vipup20.exe now

Download Vtcpup20.exe now

Microsoft scanned this file for viruses. Microsoft used the most current virus-detection software that was available on the date that the file was posted. The file is stored on security-enhanced servers that help to prevent any unauthorized changes to the file.

To work around this behavior, revert to Winsock 1.1 by uninstalling the Winsock 2 Update. To do so, double-click the Ws2bakup.bat file located in the :\ \ws2bakup folder, where   is the drive letter on which the Windows folder is located, and   is the name of the folder in which Windows is installed.



MORE INFORMATION
When you install the Winsock 2 Update but do not update TCP/IP, the Inetcomm.dll file is not updated to a version that is compatible with the Winsock 2 Update. When you install the Vipup20.exe and Vtcpup20.exe files, the Inetcomm.dll file is properly updated.

For information about how to obtain the Vipup20.exe and Vtcpup20.exe files from the Microsoft Download Center, please see the following articles in the Microsoft Knowledge Base:
