iis ftp : New ISP now can't connect

We just changed ISP's to get a faster connection (bonded T1 3.0 mbps
circuit). Our new ISP is hosting our DNS and has correctly (I think) setup
an A record for ftp.

Our web and ftp servers are on the same box and run off the same IP. Web
access is having no problems but ftp access no longer works.

We are running IIS5 on a Windows 2000 server and do not have anonymous
access enabled. Even with anonymous access we still get the same error
accessing the site.

From Internet Explorer we get the 'FTP Folder Error: Windows cannot access
this folder. Make sure you typed the file name correctly and that you have
permission to access the folder. Details: The connection with the server was
reset.' 3rd party FTP programs give a similar error when trying to connect.

Everything was working fine before the ISP (and IP change). Everything else
on the network including internet and mail access is working fine, just no
FTP.

I've tracert'd to the ftp address and there are no problems there so I'm
asuming something on the server configuration is fouled up.

It's really your ISP's problem, noting you can change. Best guess is
a firewall port didn't get opened (which you can check on your
outbound firewall), or FTP just isn't configured correctly. Call your
ISP and ask them to help.

check the ftp site configuration and be sure it is listening to the proper
ip address or 'all unassigned'. also to check the server itself try to use
the windows ftp program from a cmd window on the server itself t see if it
is running properly and if it responds to the localhost and external ip
addresses. you can also try to put another machine on the server side of
the router temporarily to test the firewall without worrying about the isp
setup, though depending on the configuration you may have to get another ip
from the isp for that box.

Try ftp locally first, if everything works, then try from remote client.
if fail, check if there's firewall rules that blocking it or new rules with
new ip not yet configure ?
