RESOLUTION

Verify that you have Inetcomm.dll version 4.72.3155.0 if you use Microsoft Windows 98 or Microsoft Windows NT 4.0. If you use Microsoft Windows 95, the correct version is 4.72.2106.4. If you have any other version, rename it, and then reinstall Microsoft Internet Explorer 4.01.

NOTE: Although the following steps apply to Internet Explorer as it is installed with Outlook 98, the same procedures apply if you are using Microsoft Internet Explorer 5.0. The version of Inetcomm.dll should be 5.00.2314.1003. If the version is earlier than this, rename the Inetcomm.dll file, and install Internet Explorer 5.0 from the following Microsoft Web site:
