We have an ISA 2000 server set up for users to access the internet. I am having problems accessing an ftp site that has authentication when going through the isa server. If the ftp site doesn't require authentication then it connects just fine. I have tried different versions on internet explorer and have tried multiple configurations in internet explorer. The ISA server is set up to allow all IP traffic.

The error I get is HTTP 502 Proxy Error - The login request was denied. Background:
The gateway could not retrieve the requested page.

This error message pops up right away. I don't even get a chance to log on.

Please help!!!

Well the problem might just eb with the ftp I have noticed that most of the ftp's on the net actually don't work for users. I have tried an ftp at this tech I goto and then tried it on my home computer and it didn't work on either of them.

As a quick test, download an ftp application and install it. Then try downloads using it, but switch back and forth between the active and passive settings. They use different port verification. If it does work, then recheck your settings on the server or firewall (if you have one). We traced one of our problems just like this, to a firewall setting. After we changed it, all was fine.
