Hello,
I am trying to access an FTP site that requires authentication. However I
receive an Error Code 502: Proxy Error. I am able to connect to some FTP
sites like ftp.microsoft.com, ftp.adobe.com, and ftp.symantec.com. However
when I try some sites requiring authentication, I get the above error code.
For instance the FTP site ftp://216.208.79.102 works perfectly outside our
LAN but on our LAN from the server and/or any client station, we get the
error code 502. We don't even get the authentication window. We get the ISA
error message with the above error code.
I just installed a new server with SBS 2003 R2 Premium Edition.
I unchecked the Read Only checkbox from both rules in ISA 2004, that is, the
'SBS FTP Access' rule and the 'SBS Internet Access' rule.
I tried connecting with 'Passive FTP' check/uncheck from my Internet
Explorer 7.0.
I am stumped!!
Your help in this matter would be most appreciated. Thank you.
