You are better of with third party solution.
in IIS 5 I think you will have the control for http and ftp service.
but then again, the throttling feature is not a good one.

with IIS6. the ftp part has been removed.

Hi Bernard,

I've checked with the setting in IIS 5 as well, I also can't find any
setting in IIS to control FTP bandwidth.

Now my production web/ftp server is running IIS 6.0, do you mean that I
can't do anything to avoid this concern if no available budget for me at that
moment? Can you also introduce any third party solution?

Thanks,
Alan

In IIS 5, I believed is at the master properties, right mouse computer name
and .....

for third party, you can try http://www.tcpdata.com/att_overview.htm and
google around.
I have not tested any though.

Thanks for your information first!

In IIS 5, according to your message, right mouse computer name I just can
limit the total no. of connection & connection timeout value in FTP Service
Master Properties but not the bandwidth throttling inside WWW Service Master
Properties. In additional, this throttling setting does not affect FTP
service in IIS 6.0. Is that correct?

For IIS 5 -
IIS MMC - Computer Node - right mouse 'IIS' tab, in the middle section -
'enable bandwidth throttling'
it read 'limit... for all Web and FTP sites....'

And yes, there's not throttling for IIS 6 ftp.

Oops, I oversee this section in IIS 5.0.

Hmm, in IIS 6.0, I think I've to find another workaround...
Anyway, Thanks Bernard.

Some firewall or router allow you to control bandwidth... or you can google
around.

Actually, I don't have any solid idea to limit the bandwidth in FTP service.
Perhaps I would like to check in detail my existing setting first as my
server is running on NLB mode. Right now, I still don't confirm the reason of
the high traffic when using FTP. It will take time to find the root cause of
it.

You can look at the ftp log file ?
see if any illegal file was uploaded or huge file was downloaded by end
users.

Yes, I'd checked the FTP log and believed the high traffic was caused by the
huge file was uploaded/downloaded by the users. And I'm quite sure such
action is normal from client side.

BTW, I'm using two servers connected to a network switch and the switch was
then connected to the backbone of our network, I'm not sure whether this
general "switch flooding" or just simply "huge file" issue. (As I know,
switch flooding only affect all nodes attached to the same switch)

Maybe, I'm not too sure on the switch flooding part.

since you have the ftp log file, you should be able to summarize the total
in / out bandwidth and compare with the bandwidth report. See if it take up
most of the bandwidth.
