Network definition doesn't recognize change in disk names/letters.

I have three computers running XP Pro, two hardwired to my router, one (a
laptop) wireless. All the disks one the various machines were defined and
shared on my home network. The disks included three external (USB) hard drives.

I have replaced two of the externals with a larger single external drive, but I
can't seem to get the new configuration through to the network.

I had drives G, H, and I. I combined the data from G and H onto the new drive
and then set the new drive to G and the old I drive to H. But when I look at
the "complete network" I still see the labels for the old G (Pictures), H
(Music) and I (Video). (I also see the label of the new G (Combined), and can
use it to map the drive on the other machines.)

If I open the nominal the Picture drive I see the contents of the new G drive,
the Music drive opens the new H (Video), while the Video throws and error (as
there isn't an I drive anymore.

How do I tell the network about the new drive labels?
