Any User Can Log on to FTP Server with Disabled Anonymous Logon (164507)
The information in this article applies to:
- Microsoft Windows NT Workstation 4.0
- Microsoft Windows NT Server 4.0
This article was previously published under Q164507 SYMPTOMS
A Windows NT 4.0 FTP server can be accessed by any user when the anonymous
logon is disabled.
CAUSE
The profile name, IUSR_COMPUTERNAME, does not require a password.
RESOLUTION
There are 2 resolutions to this issue:
- Set up the user, IUSR_COMPUTERNAME, with a password in User Manager for
Domains.
Because an anonymous logon is not allowed, putting a password on this
account will not affect anything but an anonymous logon. This user
account is set up specifically for Internet Server Anonymous Logon.
NOTE: If you change the password for this account in User Manager for
Domains AND you have a World Wide Web Server on the same computer, you
will need to run Internet Service Manager. Double-click the WWW service,
and change the Anonymous Logon Password for the IUSR_COMPUTERNAME user
to what you changed it to in User Manager for Domains. This way, users
that connect to your WWW Server anonymously can get access to the page.
-or- - Apply the hotfix mentioned in this article.
