Mark works as a Network Administrator for NetTech Inc. The company has a Windows 2003 Active Directory domain-based network. The domain consists of four domain controllers, six Windows 2003 member servers, and 500 Windows XP Professional client computers. Mark finds that the computers on the network are occasionally performing slowly because of malicious worms that are coming as Microsoft Visual Basic scripting edition files. He investigates the client computers and finds that VB Script files have been downloaded by using Microsoft Outlook and peer-to-peer file sharing programs. Mark wants to prevent users from running VB Script files regardless of how the worms come on the client computers. What will he do to accomplish the task?
