A single machine with SetiQ and the client on the same box, right? Did you try the loopback address (127.0.0.1) so it looks for WU's from itself? I haven't done this so I'm kinda guessing. Okay, it's a total guess but it's reasonable, right? 😉

Edit: Try pinging loopback or 127.0.0.1 first before trying. As long as you've got TCP/IP setup it should work, I think. 😉
