We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS

After you set the LowercaseFiles registry parameter to either 0 or 1, the FTP commands to retrieve files behaves in the following manner:

"GET" is not case sensitive
"MGET" is case sensitive

CAUSE

The LowercaseFiles (REG_DWORD) parameter is for display purposes only. The following is an excerpt:

   LowercaseFiles                                  REG_DWORD
   Range:  0 or 1                                  Default:0
   Description:                                    CONFIGURABLE

   The service uses the native case for file names (like what the file
   names are stored in file system). However for exact comparisons with
   case-sensitive file systems (NTFS provides an option, FAT is case
   insensitive) to work fine, it may be necessary to ensure proper file
   names are used. Administrators can turn on this flag to ensure that the
   service uses lowercase for such comparisons.
