SYMPTOMS
========

When you configure a Microsoft Windows NT user account to be used by clients
using HTTP basic authentication, Internet Information Server (IIS) requires that
the account is granted the Log on Locally right.

If this right is not granted to users who will be accessing IIS services, then
the following symptoms may be experienced.

When a client tries to access an HTML page on IIS, you will get the following
error message:

  Error: Access is denied.

When a client tries to access the FTP server on IIS, you will get the following
error message:

  Login failed.

However, for reasons of security, it may be undesirable for the IIS Administrator
to grant users the Log on Locally right.

RESOLUTION
==========

Microsoft has created a patch that enables IIS administrators to choose which
right needs to be granted to users in order that clients using Basic
Authentication may access IIS services.

After you apply the patch, the required rights are configurable by the IIS
administrator by setting the following registry value (where ServiceName is
either W3SVC for the WWW service, or MSFTPSVC for the FTP service).

WARNING: Using Registry Editor incorrectly can cause serious, system-wide
problems that may require you to reinstall Windows NT to correct them. Microsoft
cannot guarantee that any problems resulting from the use of Registry Editor can
be solved. Use this tool at your own risk.

HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet
 \Services
  \ServiceName
   \Parameters

Value Name: LogonMethod
Value Type: REG_DWORD
Value Range:   0 or 1
Default: 0

A value of 0 means users must have the right to Log on Locally to be given access
to the server. A value of 1 means that users must have the right to Log On as a
Batch Job.

The Log On as a Batch Job privilege is an advanced user right that may be granted
in User Manager.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft Internet Information
Server version 1.0. This problem was corrected in the latest Windows NT 3.51
U.S. Service Pack. For information on obtaining the Service Pack, query on the
