Hi,
Sorry about the Vista references, I was taking it for granted most people these days were moving in that direction.
From what I remember, If you open Windows Explorer and right click on My Documents at the top, you should see a target tab at the top and the path further down. I'm on XP Pro at the moment and it doesn't seem like you can change the path of My Pictures or My Music the same way.
I don't think I'd want to create a My Documents structure on your server, as when you add or change other peoples location to the same area, it asks to move files over. So I'd be cautious about overwriting what's already there. As I said earlier, I'd just map a drive as I'll show you below.
Do you have the shared folders from Windows connector software on the desktop. Can you right click on it and Map Network Drive? If not.
Open Windows Explorer and go to the bottom and select My Network Places, right click on it and explore, then workgroup (or whatever your workgroup is called). You should see the shares here under the server name (WHS computer name). Right click on shares or each folder if you wish and select Map Network Drive, then select a drive letter (it will normally be Z: and work back up the alphabet from there) and make sure re-connect on login or whatever is ticked.
As long as you have your pictures etc. backed up, you can play and see what happens. I'm sure you could change the path of My Videos & My Music with Tweak XP or in the registry, which is all Tweak XP does anyway really.

TweakUI and where to find My Pictures etc.
