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:

SUMMARY
According to RFC 959, there are three transfer modes in the File Transfer Protocol. The following codes are assigned for toggling the transfer modes:

S - Stream

B - Block

C - Compressed

The default transfer mode is Stream. Internet Information Services (IIS) only supports Stream mode transfers in its current and earlier implementations.
