My IIS7 stop working on passive mode from time to time …
Dear experts,
I have a Windows 2008 server with IIS7 which I use for FTP server. All working fine, but recently I get follow problems: the IIS7 is set to work in passive mode before 4 months and it work fine until 2 weeks.Now - after download few files, or after few hours or days it stop working in passive mode, but working only in PORT mode. The interesting is that no any human send any action to server. After restart of FTP service or on all Windows 2008 it starts working in passive mode.
What could be the problem and what settings I should do? I check, my settings in firewall are not changed.
This is some bug in Windows 2008? It will help if I go to Win 2008 R2 ?

Well, this may be the case, because before 4 weeks suddenly the firewall settings have been reseted and I manually open 15 ports for that in firewall, it is possible the FTP server to be to use 20 ports …When next time the server goes to PORT only mode I’ll check which port is reported for Passive mode.
Meantime I execute this command on server:
netsh advfirewall set global StatefulFtp disable
I’m not quite sure what this command do, but it may help?
And I have other question – as I see you look like expert. Does IIS 7.5 in 2008 R2 is with better reliability then the IIS7.0 in Win 2008 /I’m interesting of FTP server only/.

At all ... what FTP server to install and use over WIndows Server? My primary demands is really working in 24/7 and with relative huge files - 10-30 GB and 100-500 files per day.
I'm little supprised of IIS7.5 because it do not support any check sum - like CRC or MD5, while my sofware application support both modes .

You might want to consider rsync if those are the same files from the same client every day just appended or slightly modified... it has the ability to only send the portion of the file that changed so you don't have to send the complete file like you do with FTP.

I should use FTP, it is not a problem because IIS7 support resume and my software download only new files.
What I need is a reliability wokring of a FTP server over WIndows /I'm limiti to windows because I have a SQL Server as well /
IIS 7.0 7.5 is reliability working? I hear from one admin - no body use IIS7 for FTP . He advice me to install third part software ... what do you think?
