第6题:
You are the network administrator for Your network consists of two Active Directory domains. Each department has its own organizational unit (OU) for departmental user accounts. Each OU has a separate Group Policy object (GPO) A single terminal server named TestKingTerm1 is reserved for remote users. In addition, several departments have their own terminal servers for departmental use. Your help desk reports that user sessions on TestKingTerm1 remain connected even if the sessions are inactive for days. Users in the accounting department report slow response times on their terminal server. You need to ensure that users of TestKingTerm1 are automatically logged off when their sessions are inactive for more than two hours. Your solution must not affect users of any other terminal servers. What should you do?()
