I've searched around a little bit on this issue, but haven't found
anything that quite suites the issue I'm having.

OES2, Latest Vista Client (this issue occurs with all versions)

In certain "open" windows it shows my network drives as disconnected,
but if I click on any of them the drive really is connected. If I click
on my computer, or computer in the start menu the drives all show
connected. I've noticed this is happening inside of IE, but doesn't
happen when using Office. Vista also seems to have issues copying files
from mapped network drives, but when I use the UNC path it works fine.
This happens on multiple workstations, and the client has been
reinstalled on a few of them.

Any ideas?
