Adding Active Directory group to shared folder in Windows

view story

http://serverfault.com – I'm trying to automate file sharing process and I started by creating some Active Directory groups for each permission: USR_TEST_GROUP_RD, USR_TEST_GROUP_WR, USR_TEST_GROUP_FULL I add some Active Directory users to those groups and added those 3 groups to the folder with their permissions but I keep gettng Access Denied message.
