Resolving problems with the Windows Firewall and FTP programs
Go into My Computer/Control Panel and right click on System. You should
be on Windows XP SP2.

Go into the Windows Firewall.

The normal setting is ON. If the screen is greyed out then they are
using an external Firewall program.
Click on Exceptions.

The program MUST show in here. If not then it must be added by clicking
on Add Program.
If it then will not add it but says that it is covered by a Group Policy
then they have a 2003 server which is automatically setting the Firewall
settings.

Click on Browse and locate the program. OK the setting.
The program is now permitted.
