After you add a computer or a user account to an Active Directory security group, the new access permissions or the new GPOs are not applied immediately. To update the group membership and apply the assigned permissions or Group Policies, you need to restart the computer or perform a logoff and logon (for the user). This is because AD group memberships are only updated when the Kerberos ticket is issued, which happens when the system boots or when a user is authenticated at logon.
