 Last reviewed: November 13, 1997
Article 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.

WORKAROUND

Please refer to the Verity FAQ ID:10218.0: "Using NT Authentication with your Search'97 Information Server 3.0 Install."
