I keep all my photos on a networked computer. On my Windows Vista Home
Premium computer, I can't get Explorer to display the thumbnails for any
picture. It only displays a generic image icon. If I open a folder on the
local hard drive, it shows the previews fine.

I've made sure that to uncheck "Always show icons, never thumbnails" in
Folder Options. I've applied the folder template "Pictures and Videos" to
the network folder.

My Windows XP computer seems to have no problem displaying image thumbnails.

How can I get Vista to display the image thumbnails on a network folder?
