Thanks for the clarification. I'm so used to only working with server-side programs, the fact that "launcher" was client-side only didn't click. I've got the Connection Manager running now, though I'm not yet sure how much it will do for us in the future.
It's just taken a little time to wrap my head around some of the ways the process works. I've read through it multiple times, but until I actually saw it "in action", I wasn't getting it. With the Connection Manager "connection", I think we've got something that will keep us going.
The web shortcut sounds intriguing, but would require a LOT of additional work on our end to get the registries updated, etc. Going with a desktop shortcut to the .windx file looks like the quickest, easiest, and most direct route.
Thanks, all, for the help!
