cannot access IIS-FTP

[Daves]

hi,
I have IIS configured for FTP to a local folder which has full permissions
for "IUSR_computername"
The same user is used for anonymous logins to my ftp server. Port 21 open on
router and in firewall.

When I connect from the Internet the ftp server is found but I cannot get
the folder contents. In IIS "current sessions" I see that the user is logged
in. So the problem *seems* to be that IUSR_computername doesn't have file
access to folder or... what can it be???

FTP requires more than just port 21. It'll need port 20 too. Port 21 is the
command port, port 20 is the data port.

If you're using passive mode in the client then high ports above 1023 will
also need to be opened.

Try http://slacksite.com/other/ftp.html for a good overview of how the
different FTP modes work.

Daniel, thx - you're absolutely right. I opened up these ports and bingo.
Having opened up 3 ports I decided it was best to open the FTP service (I'm
of course talking about the Windows firewall not the router)

Thank you!
