Ever since my company installed a Windows 2000 server we can no longer connect via ftp to our Cobolt Raq3 web server from within the company. If I try to connect from home I have no problem, if I try to connect from work it times out. The web server runs apache (not sure which version) on Red Hat 5.?.

Don't worry about giving a technical answer, I may be new to linux but I've been working with computers since before Windows existed. Give me a command line over point and click any day. :)

Solving something like this is difficult without knowing the specifics of
the situation. I'm assuming the box that was upgraded to win2k is the
firewall, right? What is the connection path to the web server from both of
your client boxes(mainly I'm wondering if you have to go through the
firewall from outside _and_ inside)? You said the firewall is set up the
same, but what _are_ those settings? Is ftp the only protocol that shows a
problem? Have you tried both active and passive mode ftp? Are you getting
_any_ connection at all(TCP syn/ack handshaking, login prompt)?
Almost the first thing I do in a situation like this is to fire up a packet
sniffer on all of the boxes concerned. You should see the initial SYN
packet leave your client box, hit both interfaces of the firewall, and show
up on the webserver. The response packet should go through them all in
reverse. If you see it disappear somewhere along the way, then that's where
you should be looking. Usually ftp problems are firewall configuration
issues, especially active ftp.
