All, We've got a copy of this book of abstracts for presentations at a chemical engineering conference in 2005: http://odin-primo.hosted.exlibrisgroup.com/und:und_all:ODIN_ALEPH006134188 It's got a CD-ROM included with the full papers for hundreds of them, and now we have a patron who wants to consult one of them. Unfortunately, we can't get the dang thing to work. The files on the disc are encrypted. There's a utility which is supposed to decrypt them, but it doesn't work. When you run the program, it starts a web browser and takes to localhost:103. After that, it times out and reports that it's unable to connect. Yes, I disabled the Windows firewall completely and tried it in multiple browsers. There are several little executable files on the CD, all of which appear to do the exact same thing -- open a failed connection to localhost:103. Executing them from the command line yielded no useful information, even using command-line switches like -h, --help, /?, and /h. None of them had any help text, though a few produced badly written HTML output claiming they couldn't access things, or that they were corrupted. I take that as an indication that my wild-ass guessing at their purposes and usage were wrong, rather than actual file corruption. I've sent an email to the company that made it (they're still around!) but thought I'd ask here also. Any insights?

To get by that you have to manually enable port 103 by putting user_pref("network.security.ports.banned.override", "103"); in your profile's user.js.
