iTunes network stuff disappeared, wth?

[jgmacrum]

A week ago the battery on my MBP died so the machine was booted from scratch. Ever since then, I've noticed that I don't see other iTunes shares from my iTunes - even after toggling sharing (from on, to off, back to on).

Today I noticed that I also don't have selectors for output - e.g. airtunes speakers and such.

What the heck did I do?

Restarted your router?

No, but this happens at work and at home.

Also probably worth noting that at home, the other computers aren't having issues like this.
