Are you on a Mac? Are you saving a PICT preview from XPress? If so, that PICT preview is not going to stay with the EPS file when you save to the server. It's a PC server and it doesn't support resource forks.
If you have never heard of resource forks, then here is the difference between PC file systems and Mac file systems. A PC will use a three letter extension to a filename and the OS uses that extension to tell it what program to open the file with. On a Mac, you don't need that (or didn't used to anyway). A Mac will store the information about it's file creator in the resource fork. The actual data in the file is stored in the data fork. But PC's don't recognize the resource fork, so when you save an EPS file (which uses resource forks on a Mac) to a PC server, that resource fork is discarded. PICT previews are stored in the resource fork. So, essentially, your preview is tossed and you get a gray box.
I'm betting it's a PICT preview because that is the default on an XPress install to a Mac. Use a TIF preview and see what happens. TIF previews are stored in the data fork.
