"Location is not available" on Vista

Ok, this is not exactly a .NET issue but I still thought it is worth mentioning it here since I assume there is a sufficient number of people currently using Vista for development who may have encountered this issue. You may have experienced one or more of the following:

• "Preparing your desktop..." for an extended period of time
• "Location is not available" after you log in
• Desktop looks more like XP and has lost the Aero look-and-feel

I don't know what the reason for this was. Maybe it was relating to my Vodem to not being able to survive stand-by and/or hibernate. Maybe it was because Vista decided to run some lengthy checks, like CHKDSK. The event logs don't give a clue.

Resolution: Reboot another time.
