Can't Activesync clicked "don't ask this again" box

[dr_hfuhuhurr]

My wife hit the "don't ask this again" on the screen that lets you select the ActiveSync, Disk Drive, or Internet Sharing.

Now I can't seem to get it to activesync. Anyone know how I can undo what she's done? I assume it's a registry setting but I can't seem to find anything.

I've searched but can't find an answer.
