Drive Mapping via Group Policy Preferences not working for Vista clients

Ok – so this has been bugging me for a while.  One Vista machine on my SBS 2008 was not having mapped drives created via the Group Policy Preferences I had established.  I could log in with the same user account on another Vista machine as well as two XP machines, and the drives were mapped as expected.  I did some troubleshooting a while back, but didn’t spend a lot of time on it since it was an annoyance for me at best.
