I am using Wondows 2000 and ISA on the same server. I am trying to set up an ftp server on that machine. The problem is I cannot get passive requests to work. I have followed the instructions in the article below which explains the procedure (gone through it 3 times) When I run the netstat -na command the server is listening on the external IP address rather than the Internal one. Is this causing the problem and if so how do I get port 21 listening on the internal IP. Thank you for any help. Matt http://www.isaserver.org/tutorials/Publishing_an_FTP_Server_on_ISA_Server.html
