There is a table in the server which keeps track of which passive ports are in use, although it won't help if another application is using the port. > Isn't it possible that winsock refuses the connection attempt due > to a full ListenBacklogQueue Unlikely, these are Windows 2000 servers running IIS/5 FTP for five years or so (and FileZilla) without any problems, I've only just changed one to use ICS FTP server now it has mode z. Looking at more logs, I see: '501 Cannot RETR. Error - Connection reset by peer (#10054)' and '501 Cannot RETR. Error - Connection aborted (#10053)' errors are coming back as well for passive downloads. But they usually work on the next attempt.
