OL98: (IMO) Outlook Caused Page Fault in Module INETCOMM.DLL

ID: Q184073

The information in this article applies to:

SYMPTOMS

In Microsoft Outlook, when you attempt to send or receive an e-mail message, you may receive the following error message:

OUTLOOK caused an invalid page fault in module INETCOMM.DLL at 0157:5e.
NOTE: In some cases the page fault has been observed to occur in Module Kernel32.dll.


CAUSE

This error message may 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.


RESOLUTION

NOTE: If you have not already installed the Winsock 2 upgrade (Wsockupg.exe), you should do so before continuing with the following steps. To resolve this behavior, run the Vipup20.exe and Vtcpup20.exe files from the Microsoft Software Library. To do this, follow these steps:

  1. Download the Vipup20.exe and Vtcpup20.exe files from the Microsoft Software Library to an empty folder on your hard disk.


  2. Double-click the Vipup20.exe file you downloaded in step 1.


  3. Follow the instructions on the screen.


  4. Repeat steps 2-3 for the Vtcpup20.exe file.


These files can also be located on our the Microsoft Web site at the following locations:   http://support.microsoft.com/download/support/mslfiles/Vipup20.exe

and

  http://support.microsoft.com/download/support/mslfiles/Vtcpup20.exe

NOTE: Because the Microsoft Web site is constantly updated, the site address may change without notice. If this occurs, link to the Microsoft home page at the following address:

  http://www.microsoft.com/

To work around this behavior, revert to Winsock 1.1 by uninstalling the Winsock 2 Update. To do this, double-click the Ws2bakup.bat file located in the following folder:

<drive>:\<windows>\ws2bakup
Where <drive> is the drive letter on which the Windows folder is located, and <windows> is the name of the folder in which Windows is installed.


MORE INFORMATION

If 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.
