Client Computers Can't Connect To External Ftp, But Server Can...

[Dawning]

Hi,

I'm administrating a server 2008 r2 with apr. 20 user pc's. Our accounting software backs up to an external FTP site. If I back up directly from teh server, there is no problem i just connects and backs up directly. But if i try the same from one of the user pc's i get a time out and no back-up :-( What is wrong?
Firewall is off on the user PC. I've tried to turn off the local virusprotection an still no luck. The server is setup with the default local policys.

I've tried to look trough all settings on the server i could think of but i'm still kind of a newbie, and therefore a little scared of touching to much :-S

The user PC's have no other problems connecting to things in general.

Is there anybody out ther who can help a damsell in distress???

Maybe the problem could be the network firewall, is there any rule which block connection on port 20 / 21? usually block port 20 and 21 except for the server which need to connect to a FTP server.
