Tre,
Open Group Policy Object Editor for the GPO you wish to edit. Expand
User Configuration, expand Administrative Templates, Click on Start
Menu and Taskbar. Scroll about half way down and you should see Lock
the Task Bar make sure this is disabled.
Then open regedit and browse to
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\
Advanced
In the right pane change taskbarsizemove from 0 to 1. You may need to
restart or logoff for the changes to take effect. Group Policy will
only allow you to prevent the user from locking the taskbar it will not
unlock it by default. The user would have to manually unlock it.
However you could write a logon script to change this regkey via group
policy.
if you need assistance with that let me know.
