AirPort Utility 6.3 does not see AirPort Express

[Cave Man]

I have a new AirPort Extreme Base Station with 802.11ac support. It is set up and running fine with my Macs in the house; however, Airport Utility 6.3 (latest version) does not see my AirPort Express, even after a factory reset. Any ideas how to get it to show up in AirPort Utility?

Edit: Rebooted my MBA and re-reset the Express and now AU6.3 sees the Express; however, after setting it up I get the perfectly meaningful and clear message in AU:

An unexpected error occurred. Try again.

Really? WTH kind of message is this?

Edit 2: I found the solution! Randomly unplug and plug-in, push the reset button for various amounts of time and eventually it'll work. Sheesh. This networking stuff is really unApple-like.

Configure Ivp6 must be on. Open the Network preference pane, click on advanced, and set it to automatic, for both ethernet and wifi. I had the same issue, fixed it for me.

Thanks for the reply. I'm afraid to do anything because it might stop working! It's been solid for the entire day, so hopefully it's good to go.
