I have installed Small Business Server 2000, using ISA Server and Exchange 2000. Exchange 2000 is running fine. However I'm unable to us FTP, both through IE and a Dos Window. All I get is host unknown through Dos and access not setup correctly from IE. I have enabled the FTP policy, the same as I have configured for another two customers but nothing (other sites work, but just w2k and ISA). There is no issue with DNS as I have tested that many times and Exchange messages are flowing fine. I decided to try a test / work around and setup an FTP server on this box also. I followed the intructions from the Shinder Section to do this and all is OK for external users coming in and authenticating. Any suggestions as to why outbound FTP fails. Regards Gary
