I have the same problem. SP4 installed.

I have an FTP object in 2 DTS packages I cannot open. I am currently remote, so I hope as others have found they can open them from where they were created.

It almost seems that to me that there is a reference to something in the package that when you are not on the same machine, it cannot access, so EM from another machine can't open the package.

No solution yet, other than use Active X vs built in FTP object
