You try to log on to an FTP site that is hosted on a server that is running Microsoft Windows Server 2003, the Active Directory directory service, and Microsoft Internet Information Services (IIS) 6.0. The FTP site is configured to use "Isolate users using Active Directory" mode. However, you cannot log on to the FTP site. Instead, you receive the following error message:
Error: 530 User UserName cannot log in, home directory inaccessible
This problem occurs only when a particular domain controller is offline or unavailable. At other times, you can successfully log on to the FTP site.
