Windows 7: Policy and Mapping drives (HELP)

Hi! Right now at work we are still mainly using WinXP and we have shared drives that automatically appear in "My Computer" once the computer is added to the network. This has been working fine in windows xp, but now we have started installing a couple of PC's with Windows 7 Ultimate 32bit, and adding them to the same network but when clicking on "My Computer" there is not a "Network Location" section showing the mapped drives that should be located in that section. it does not show the mapped shared drives that are auto shown in XP when set up on the network. I have made sure network and file sharing are turned on and it is added to the domain because I can connect to the workstation across the network and it shows that it is on the domain. I am sure there is something I am overlooking. Can anyone help me with this?

Your group policy will be the cause of this until upgraded to 2008 server or updating your GPO.
This article touches on it a bit: Windows 7 clients on 2003 domain / group policy

All of our domain controllers are 2008 server. What do you mean by "updating your GPO?" Thanks for the advice.

Are your win 7 desktops pulling any other Group policy rules? ie: desktop policies & user policies?
If it's just the mapped network drives failing, checkthe NETLOGON for the .vbs or .bat that should be mapping these drives. I've seen issues with the .vbs scripts not running correctly... The .BAT mappings definately work.

you may have to add a delete line to the bat file:
net use x: /delete /y
net use x: \\server\sharename
