This one really has me stumped.
I took over administering the network for this small business a couple of years ago. They are trying to setup their website (located off-site) and need to FTP to the host server to upload the site content. For some reason they are unable to FTP from any computer running 2000/XP. They have an old computer running 98 or Me (can't remember) and it is able to FTP just fine. This is not isolated to this particular site. I have tried Dell's FTP site, Symantec's, and they have tried several others specific to the services they provide. There are a few FTP sites that they can connect to using a 2000/XP machine, but most will not work except on 98/Me.
Single server running Windows 2000 SBS.
Server is configured as router/firewall, running ISA 2000.
Two switches on the network.
Most machines running XP, a couple run 2000 and one runs 98/Me for old legacy app (RealWorld).
I have gone through ISA and made sure FTP is available for port 21 inbound and outbound. XP firewall is turned off. I have even tried going through GPO's to see if that is having an effect and could't find anything. I tried searching some on Google, but couldn't find anything similar to what the user's are experiencing. The only thing I did find was from Microsoft and it didn't work:
To enable folder view for FTP sites, use the following steps:
1. Start Internet Explorer.
2. On the Tools menu, click Internet Options.
3. On the Advanced tab, click to select the Enable folder view for FTP sites check box.
If you can figure this one out you deserve some points!
