Verity Search '97 Causes IIS Authentication to Fail

ID: Q172140

The information in this article applies to:

Microsoft Internet Information Server version 3.0

SUMMARY

Internet Information Server (IIS) systems with Verity Search '97 installed may fail with the following symptoms:

Verity Search'97 fails to operate with Anonymous password authentication disabled.

No users (except administrators) can authenticate with Basic (Clear Text) password authentication, while NT Challenge/Response works fine.

No users can access secure NTFS directories, including administrators.

CAUSE

Verity Search'97 installs a new authentication filter in the Microsoft Windows NT Server system registry. This filter, Authfilt.dll, is installed by Verity Search'97 in:


   \\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
   Services\W3SVC\Parameters

According to Verity, this filter fails to work correctly with IIS.
