a couple of things to try.
Under admin management of serv-u double click your user name and then click the dir tab.  Make sure you have at least read/write access to the folder.
under domain/settings click advanced tab and make sure passive mode data transfers are enabled.
If you are using third party firewall try disbling it to see if this cures the problem.  If so you need to add exceptions for ports 20 and 21.  (in and out)
Also make sure you have set up port fowarding for port 20 and 21 in your router.
If you are trying to access your server from your server via http---try accessing it from a pc in another location--seperate from your network altogether.

Also under local server settings-advanced tab, uncheck auto configure upnp firewalls.  Recheck the firewall port translation settings--port 20 and 21 have to be fowarded.
hope this help.  I just finished setting up my u-ftp sever behind a pix 506e with pc-cillin.  It took some tweaking but it works great now.  If none of this helps-I will keep trying to help get yours working.

This issue is will be resolved if you install the Microsoft Firewall client on your computer. Since if you are accessing the Outside FTP it requires Secuirty. Hence Please install the Microsoft Firewall client and check if you are able to access the site.

In order to download the Microsoft Firewall client Please access the below mentioned URL:

http://www.microsoft.com/downloads/details.aspx?FamilyID=45855498-66ba-43d3-a8f1-37837d380389&DisplayLang=en

Once you install please restart the computer and then try accessing the FTP Site.

Good luck, Get back to me if you have any issue.

Check whether both ports 20 and 21 are open. It looks like port 20 is blocked.

Check Internet Explorer's settings in the advanced tab.  Is see if you have "Use Passive FTP", checked.  If it is checked uncheck it.  If it unchecked, check it.

This controls which type of data connection IE will use, active or passive.  Both types use port 21 for the command/control session.  

When using active the sever uses port 20 as the source and it (the sever) inititates the connection to the client. The client listens on a random port above 1023.

When using passive the client , using a random port above 1023, connects to the sever which is listening on a random port that is abovr 1023.
