Both of these tasks can be created using Group Policy Preferences. Go to User Configuration | Preferences | Windows Settings. You will find an icon for Drive Maps and one for Shortcuts. Create a separate GPO for each function and assign them both to the OU that contains the user accounts. Then make sure that the GPO for the Drive Maps is listed ABOVE the GPO for Shortcuts. This will ensure that the Drive Map GPO will be implemented first which is essential for the two to work in cohesion.
