FTP Server Does Not Allow FTP Server-to-Server Connection (246173)
The information in this article applies to:
- Microsoft Internet Information Server 4.0
- Microsoft Internet Information Services 5.0
This article was previously published under Q246173 SYMPTOMS RFC 959 allows for the use of the PORT command, a remote
connection to another TCP\IP over a passive connections, to be established
based on the port address given by client. This is commonly done with FTP
server-to-server transfers. This behavior was made optional to provide added
security to the FTP service.
The FTP service compares the IP address
that makes the connection and the address issuing the PASV command. If they are
different, the FTP service does not allow the connection. When you attempt to
do this on the Microsoft FTP Server, this operation fails, regardless of the
settings. RESOLUTIONWindows 2000To
