DOCUMENT:Q137853 08-AUG-2001 [winnt] TITLE :Guest Account Allows FTP Users Access Without Authentication PRODUCT :Microsoft Windows NT PROD/VER:3.51 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Workstation version 3.51 - Microsoft Windows NT Server version 3.51 ------------------------------------------------------------------------------- If a Windows NT FTP server has the guest account enabled with no password assigned, anyone can log on to the server using FTP without knowing a username or password. This situation occurs even if the FTP Server Service is configured for "Allow Anonymous Connections" using a username and password. To prevent unauthorized connections to the FTP server, do one of the following: - Disable the guest account. - Place a password on the guest account. - Configure the FTP Service to Allow Only Anonymous Connections by placing a username and password on the account. For more information on configuring the FTP Server Service, see Chapter 7, "Using the Microsoft FTP Server Service," in the Windows NT Server "TCP/IP" manual.
