IIS5: FTP Logon Fails for Passwords with Beginning Space or Spaces (303000)


The information in this article applies to:

  • Microsoft Internet Information Services 5.0
This article was previously published under Q303000

SYMPTOMS

When you attempt to use a password that contains a beginning space or spaces to log on to a File Transfer Protocol (FTP) site, you may receive the following error message:
530 The user cannot login

CAUSE

FTP server removes all the spaces between the command (PASS) and its argument (password), which leads to the removal of the beginning space or spaces of the password. Because a wrong password is passed into local security agent, the logon fails.

To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
