What should you do?

You are employed as the network administrator at Domain.com. The Domain.com network consists of a single Active Directory forest that contains a single domain named Domain.com. The functional level of the forest is set at Windows Server 2008.
During the course of the day you receive an instruction from the CIO to create a global distribution group as well as adding users to it. After creating the global distribution group and adding the users you create a shared folder named KINGDATA on a Windows Server 2008 member server. Thereafter you place the global distribution group in a domain local group that has access to KINGDATA. To ensure productivity you need to make sure that all users are able to access KINGDATA.
