Hi Bernard

In IIS Managers on my W2003 server, ftp is set to port 21. Behind the NAT
all clients computer start FTP session with port 21
using command like ftp://81.56.xx.xx
Remote FTP server ( W2000 Server SP4) use also port 21

I saw this 2 KB articles from microsoft but could'n find any solution in it.
I'm just dumb enough to don't understand it :(

More precision: in past my W2003 Server used ISA 2000 for a while but for
some compatibility issue with company software I have had to remove it.
I know that ISA server just adore to change http port from 80 to 8080 in
IIS. Does he change FTP port also?

Format & reinstall of my W2003 server is impossible (they'll kill me
 :-/ ) but i can make any kind of test during the night with possibility
to use Disaster Recovery if Server crash.

Q? how can I find out which ftp port my server use when he act like client
and NAT for others LAN users.
