Please try to be more precise. I am having difficulty understanding
what you mean and this makes it hard to help you.

When you say you tried a CGI FTP client, are you talking about using
Net::FTP from a perl script? What is the error message?

When you say HTTP works, do you mean that you can activate a script
through CGI that will then get information from somewhere else via
HTTP (I assume with LWP)?

If you can use LWP, but not Net::FTP or DBI, that is very strange.

DBI and Apache shouldn't have any interface. Apache calls on perl
which deals with DBI.

Looks good.

What is in C:\Perl\Bin? Is this ActiveState?

What is this "E:\Cygwin"?

Why do you have a cygwinb19.dll and a cygwin1_old.dll hanging around?

Having ActiveState and old versions of the Cygwin DLL lying around are
going to confuse things. Your E:\Cygwin indicates that you might even
have an old version of the rest of Cygwin. 

My advice:

1) Delete and reinstall Cygwin, and don't mount old copies.

2) Take ActiveState out of your path in Cygwin if you want to use
   Cygwin perl.

3) Try to use some kind of Net functionality on your new Cygwin/perl
   installation calling both from Apache and the shell. If it still
   fails, provide the simplest possible testcase.

Good luck.
